Expository writing is

A. fact-based explanatory writing.

B. fictional creative writing.

C. persuasive opinionated writing.

D. subjective autobiographical writing.

Expository writing is, indeed, a fact-based explanatory writing. As a matter of fact, this kind of writing gathers information and presents ideas on strict scientific conditions. For instance, expository writings are most likely to justify events by making use of a cause-effect logical conception, instead of considering the possibility of a non-straight logical answer. Unlike other sorts of composition, expository writing is the correct choice when you just want to carry out a fact-based informing exposition.
