It is morally wrong to vote. which type of claim is this

Options:

A. claim of fact
B. claim of definition
C. claim of policy
D. claim of value 

The answer would be option D "claim of value." A claim of value is a claim that is used when a person makes a  judgment, express approval or disapproval, or attempt to prove that some action, belief, or condition is right or wrong. So, in this case the person is saying is wrong to vote which is stating's that this is wrong which would mean it's a claim of value.

Hope this helps!
