All are grammatically correct.

Sentences 1 and 3 are most commonly used.

Let's analyze the grammaticality of the given sentences and pay attention to the use of "kind," the verbs "do," and "take."

1. "We asked 100 students 'What kind of exercise do you do?'"

This sentence is grammatically correct. The word "kind" is used correctly, and the verb "do" is appropriate in this context.

2. "We asked 100 students 'What kind of exercise do you take?'"

This sentence is grammatically correct as well. The word "kind" is used correctly, and the verb "take" can also be used to describe participating in a certain type of exercise.

3. "We asked 100 students 'What kinds of exercises do you do?'"

This sentence is also grammatically correct. The use of "kinds" conveys the idea of multiple types of exercise, and the verb "do" is suitable in this context.

4. "We asked 100 students 'What kinds of exercises do you take?'"

This sentence is not grammatically correct. The verb "take" is not commonly used to refer to doing exercises. A more appropriate verb to use in this context would be "do."

In summary, sentences 1, 2, and 3 are grammatically correct, while sentence 4 is not. It is important to pay attention to the appropriate use of "kind" and choose the correct verb ("do" or "take") based on the common usage.
