Each team of business students are responsible for creating a marketab

I would say "D" is the correct answer as the respective plural/singular endings are correct.

However, it seems there is something wrong with the original version of the sentence, seems like there are duplicated elements.

You are absolutely right, edited. Thank you.

(A) and (B) can be rejected as there is S-V issue...

(C) is wordy

(E) Responsible to is idiomatically incorrect , hence rejected....

Thus, Correct Answer must be (D)

Each ---> Hence, verb needs to be singular. 'is' will be correct - A & B eliminated.

E is eliminated as "for creating" is the apt usage here and not "to create" - "to create" usage is used when there is a 'purpose' behind the act.

For eg. Diversity is encouraged in schools [in order] to increase exposure.

Between C & D, C is awkward as well as distorts meaning slightly. Hence, D is the correct choice.

Meaning Analysis:
Each team of business students (subject) are (verb) responsible
for creating a marketable business plan.

so the sentence is saying that a team is responsible for creating a business plan and that plan should be marketable

Error analysis:

a) Subject verb pair: Each team of business students is a singular subject and will be taking singular verb. [note: SANAM rule: Some, Any, None, All and Many; they all take plural, other than them will mostly be singluar]

b) tense is ok, modifier ok, pronoun - none, other-none, parallel -none, idoim: correctly used "responsible for"

choice a and b can be eliminated due to s-v error
choice c is verbose, creating a plan that is able to be marketed is wordy and nonsensical
choice e has idiom error
