D. Te ponías

Someone will be glad to check your answer.

A.

se pusiera

To determine the correct choice, let's break down the sentence and analyze the verb tense and subject agreement.

The sentence structure is a recommendation in Spanish, indicating that the verb should be in the subjunctive mood. In this case, we need to use the third person singular or plural form because the subject "la clase" is a singular noun.

Let's examine the options:

a. Se pusiera: This is the correct answer. It is in the third person singular, subjunctive form, as indicated by the pronoun "se" before the verb and the conjugation "pusiera."

b. nos ponemos: This is not correct because it uses the first person plural form instead of the third person form. It indicates that "we" put ourselves in shape, which doesn't match the sentence structure.

c. Se ponen: This is not correct because it uses the third person plural form instead of the singular form. It indicates that "they" put themselves in shape, which doesn't match the sentence structure.

d. Te ponías: This is not correct because it uses the second person singular form, indicating "you" put yourself in shape, which doesn't match the sentence structure.

Therefore, the correct choice is a. Se pusiera, which means "be put in shape" in English.
