Apparently reasonable or probable (9)
I believe the answer is:
plausible
I believe this is a double definition.
'apparently reasonable' is the first definition.
(I've seen this before)
'probable' is the second definition.

(Other definitions for plausible that I've seen before include "Make us pliable so as to be convincing" , "Reasonable on the face of it" , "Apparently reasonable or probable" , "likely" , "Specious" .)
