The first thing you have to determine in this sentence is what is being compared. Time is being compared, as in today x is more effective than x was ten years ago.
You are not comparing the vaccine to ten years ago. That eliminates choices A, B and D. Choice E has an unnecessary preposition, ‘in’. Choice C is the correct

Find 3 : 2 split --> Comma + verb-ing = Modifies the preceding clause ( Only A and C remains )

Errors in other options (Comparison) marked in red, answer must be (C)

Agreed that "to form " (Infinitive form) purpose of something , however check carefully the intended meaning of the sentence and also the comparison error (As referred to in option D)

vaccine much more effective than 10 years ago : VAccine can not be compared to 10 years ago

A correct comparison must be Vaccine of the present day, compared to vaccine 10 years ago

Hello Abhishek,

Absolutely, option D has the comparison error. After reading the sentence, I figured out two errors - one is the wrong usage of verb+ing form(Making) and another one is the comparison error.
So basically, my doubt is that somehow verb+ing form is correct here. Could you please explain?

I believe the best answer is - The pharmaceutical company should add many new strains of the disease to Prevnar to make the vaccine much more effective than it was 10 years ago.

comma + verb ing usage is vorrect as it correctly modifies the previous clause

MANHATTAN REVIEW OFFICIAL EXPLANATION:

You are not comparing the vaccine to ten years ago. That eliminates choices A, B and D. Choice E has an unnecessary preposition, ‘in’. Choice C is the correct answer.
