D) Yes, because each student will have only one answer for the number of children in his/her household.

Explanation:

Jason's math teacher asked every student in the class to write down how many children live in his/her household.

Yes, the following is an example of a function because each student will write just a single value and not two or three or more as the number of children in there household are some number.

( Also Function is a mapping that maps every element of one set to the unique element of the other set).
