In a rapidly changing society, modern artists questioned and
a. government; conventions
b. politics; authority
c. tradition; conventions
d. tradition; politics

C. Tradition; conventions.

Explanation:

Modern artists question those things in a rapidly changing society because they wanted to change the status quo of the culture and therefore they challenged tradition and conventions that they see are old fashioned. Modern Artists that do these types of inquiry are trying to make the audience think about why those things are done in that way instead of another.
