Dear Friends,
Here is a detailed explanation to this question-
Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of this sentence is that the annual cost of Jane's weekly yoga class is $3,600, and it has not changed for over a decade.
Concepts tested here: Subject-Verb Agreement + Meaning + Modifiers + Awkwardness/Redundancy
A: This answer choice incorrectly uses "that" to refer to information that is not needed to preserve the core meaning of the sentence; this information is the fact that the annual cost of the yoga class has not changed for over a decade; please remember, “that” is used to provide information needed to preserve the core meaning of the sentence, and the “comma + which” construction is used to provide extra information. Further, Option A uses the needlessly wordy construction "that has not changed...is $3,600 a year", leading to awkwardness and redundancy. Additionally, Option A redundantly uses the "annual" alongside "a year", leading to further awkwardness; this usage is redundant because both terms convey that $3,600 is how much the class costs over a year.
B: Correct. This answer choice correctly refers to the singular noun "cost" with the singular verb "has been". Further, Option B correctly uses "For over a decade" to modify "annual cost", conveying the intended meaning - that the annual cost of the weekly yoga classes has not changed for over a decade. Moreover, Option B uses the phrase "annual cost"; the inclusion of the term "annual" conveys the intended meaning - that the weekly yoga class costs $3,600 a year. Additionally, Option B avoids the modifier error seen in Option A, as it does not make use of the word "that". Besides, Option B is free of any awkwardness or redundancy.
C: This answer choice uses the needlessly wordy construction "which has not changed...is $3,600", leading to awkwardness and redundancy. Additionally, Option C redundantly uses "annual" alongside "a year", leading to further awkwardness; this usage is redundant because both terms convey that $3,600 is how much the class costs over a year.
D: This answer choice incorrectly refers to the plural noun "costs" with the singular verb phrase "has not changed". Further, Option D alters the meaning of the sentence through the phrases "The costs" and "$3,600"; the omission of both "annual" and "a year" incorrectly implies that the weekly yoga classes cost $3,600 each; the intended meaning is that the weekly yoga classes cost $3,600, each year.
E: This answer choice alters the meaning of the sentence through the clause "Jane's weekly yoga class costs $3,600"; the omission of "a year" and the absence of an adverb along the lines of "annually" incorrectly imply that the weekly yoga classes cost $3,600 each; the intended meaning is that the weekly yoga classes cost $3,600, each year. Further, Option E incorrectly modifies "$3,600" with "which has not changed in over a decade", illogically implying that the sum of money "$3,600" has not changed for over a decade; the intended meaning is that the cost of the weekly yoga classes has not changed in over a decade; please remember, when “which” is preceded by a comma, it refers to the noun immediately before the comma.
Hence, B is the best answer choice.

OFFICIAL EXPLANATION
The annual cost, that has not changed in over a decade, of Jane's weekly yoga class is $3,600 a year.
A. The annual cost, that has not changed in over a decade, of Jane's weekly yoga class is $3,600 a year
Incorrect.
This answer choice has two mistakes. The first is grammatical: the relative pronoun that cannot follow a comma.
What helps us identify this question as a Relative Clause question as well as identify the mistake is the following Stop Sign:
- who, which, that, whose, whom
The second mistake is using both annual and year, which creates redundancy.
B. For over a decade, the annual cost of Jane's weekly yoga class has been $3,600.
This answer choice corrects the Relative Pronoun error and the Redundancy error of the original sentence. Moving for over a decade fixes the error of placing a comma before that and removing a year fixes the redundancy created by annual cost...year.
C. The annual cost, which has not changed in over a decade, of Jane's weekly yoga class is $3,600 a year
Not quite.
By replacing that with which, this answer choice corrects one of the two original mistakes. However, it repeats the second original mistake: using both annual and year creates redundancy.
D. The costs, which has not changed in over a decade, of Jane's weekly yoga class is $3,600
No, that's not it.
While this answer choice corrects both original mistakes, it is grammatically incorrect. The plural subject costs does not agree with the singular verbs has and is.
E. Jane's weekly yoga class costs $3,600, which has not changed in over a decade.
While this answer choice corrects both original mistakes, it is illogical. The relative clause which has not changed in over a decade follows $3,600, implying that this sum of money has not changed in over a decade, but, in fact, the cost of Jane's weekly yoga class is what hasn't changed.
What helps us identify this mistake is the following Stop Sign:
- who, which, that, whose, whom
Also, omitting both annual and year results in meaning loss.
