Choices

Choice-A

Choice A is incorrect. It uses the wrong verb form “thrown”, which is a past participle and cannot follow “to”. Using the wrong form disrupts the natural flow or breaks the flow of the idiom. Here — the structure “decided to _” requires the base form (throw). Hence, to fix it, change “thrown” to “throw” so the phrase reads “decided to throw in the towel.”

Wrong No change

7

Choice-B

Choice B is correct. Correct base form after “to.” Keeps the idiom intact and grammatically consistent. Follows standard usage of conventional expressions after “decided to.”

Correct throw in the towel

8

Choice-C

Choice C is incorrect. Simple past tense "threw" doesn’t fit after “to.” Verb tense mismatch breaks grammar rules and makes the idiom incorrectly used.

Wrong threw in the towel

9

Choice-D

Choice D is incorrect. Gerund form "throwing" is incorrect after "decided to." It doesn’t match the sentence’s required verb structure and breaks idiomatic use.
