Question

_____ do not have question marks-they are a statement that refers to a question, but they aren't actually asking a question.

a. indirect question
b. tag question
c. polite request
d. commands

I thought a, someone else said d. What do you think and why?

Answer 1

C. A Polite request is the answer in my opinion becuase an indirect question is still a question being asked rather than a statement, a tag question is also a question and a command woulnt be told as a question. 

Answer 2

D. because a sentence without a question mark means to command so the answer is D
