OFFICIAL EXPLANATION
Introduced into the College of Engineering only five years ago, ergonomics have by now become an extremely popular specialization; this trend can be partially understood as reflecting safety's importance in the workplace.
(A) have by now become an extremely popular specialization; this trend can be partially understood as reflecting safety's importance in the workplace
Incorrect.
This answer choice is grammatically incorrect. The plural verb have...become does not agree with the singular subject ergonomics.
What helps us identify this question as a Subject Verb Agreement question as well as identify the mistake is the following Stop Sign: A pseudo plural subject
Like other words describing a discipline or profession, e.g. mathematics, physics, or economics, the word ergonomics is a singular noun.
In addition, the phrase safety's importance is ungrammatical. Expressing possession using 's is only allowed with concrete (that is, tangible, or not abstract) nouns.
(B) has by now becoming an extremely popular specialization; this trend can be partially understood as a reflection of safety's importance in the workplace
Incorrect.
While this answer choice corrects the original Subject Verb Agreement mistake by changing the plural verb have to the singular verb has, it introduces another grammatical mistake by changing the V3 form become to the V+ing form becoming.
The verbal construction has...becoming is grammatically incorrect. It mistakenly mixes different parts of two different tense forms: have/has which is used to construct the Present Perfect (together with V3 forms), and the V+ing form which is used in the Progressive tense (with the verb to be).
In the current sentence the use of the Present Perfect (if correctly formed with has/have + V3) would be appropriate: ergonomics started to become popular since the specialization began at the college five years ago (in the past), and this trend is relevant/continues into the present.
In addition, the phrase safety's importance is ungrammatical. Expressing possession using 's is only allowed with concrete (that is, tangible, or not abstract) nouns.
(C) have by now becoming an extremely popular specialization; this can be partially understood as a reflection of the importance of workplace safety
Incorrect.
This answer choice repeats the Subject Verb Agreement in the original sentence: the plural verb have does not agree with the singular subject ergonomics. In addition, this answer choice introduces another grammatical mistake by changing the V3 form become to the V+ing form becoming.
The verbal construction have...becoming is grammatically incorrect. It mistakenly mixes different parts of two different tense forms: have/has which is used to construct the Present Perfect (together with V3 forms), and the V+ing form which is used in the Progressive tense (with the verb to be).

(D) having now become an extremely popular specialization; this can be partially understood as a reflection of the importance of workplace safety
Incorrect.
While this answer choice eliminates the Subject Verb Agreement mistake in the original question by changing the plural verb have into the non-conjugated V+ing form having, this change creates a new grammatical mistake, by turning the sentence into a fragment.
Think of the semicolon (;) as separating two full sentences. Each sentence needs a conjugated verb.
(E) has now become an extremely popular specialization; this trend can be partially understood as reflecting the importance of workplace safety
This answer choice corrects the Subject Verb Agreement mistake in the original sentence by changing the plural verb have to the singular verb has.
In addition this answer choice corrects the ungrammatical use of the possessive in the original sentence by changing the phrase safety's importance to the importance of (workplace) safety. Remember that expressing possession using 's is only allowed with concrete (that is, tangible, or not abstract) nouns.
