Hint: To find out the answer for this sentence one must be very thorough with the topic tenses as well as verbs. Tenses denote the time an action takes place. There are three types of tenses. Verbs are known as action words.

The given sentence is in the past tense.

Let us discuss the given options one by one.
>Option A) to catch
This option is incorrect because the sentence is in the past tense and to catch is the present tense.
>Option B) catching
This option is incorrect because the sentence is in the past tense and catching is in the present continuous tense.
>Option C) to have caught
This option is correct because it satisfies the rules of grammar and follows the tense of the tense which is the past tense. The answer is to have as we use the infinite form of the verb ( to + root verb ) when one verb is already conjugated was.
>Option D) to caught
This option is also incorrect as the phrase is not grammatically correct.

Hence option C is correct.
