Not sure how you can pick "other" from those options, but there you have it. (Physicalism implies non-dualism. Non-physicalism does not imply dualism.)

Since they didn't ask about dualism directly, nor, as far as I can tell, any position that logically entails dualism, obviously there is no deductive implication here.
I'm making a probabilistic point - non-physicalism is heavily represented (more than a quarter) among the group Samd specified, and thus there are pretty good odds that at least one academic philosopher espouses the specific non-physicalist theory of dualism.
