Answer 3

The correct answer to the question is D) to put.

Explanation: The sentence "I've lost my key. I ought ________ it in a safe place" requires the verb form that matches with the subject "I" and the tense of the sentence. In this case, the verb form "to put" is the correct choice because it matches with the subject "I" and is in the infinitive form, which is appropriate for expressing an action that should have been done in the past.

Here is the breakdown of the options:

A) that I put: This option is incorrect because it uses the past tense form "put," which does not match with the present perfect tense of the sentence.

B) to be putting: This option is incorrect because it uses the present continuous form "to be putting," which does not match with the past tense of the sentence.

C) to have put: This option is incorrect because it uses the present perfect tense form "to have put," which does not match with the past tense of the sentence.

D) to put: This option is correct because it uses the infinitive form "to put," which matches with the subject "I" and is appropriate for expressing an action that should have been done in the past.
