The answer is B, at least I think.
The definition of explicit is,“to fully and clearly express something, leaving hing, leaving nothing implied.” Something is explicit when it is cleared stated and spelled out and there is no room for confusion, as in the writing of a contract or statute.
So, explicit evidence is information directly stated in the text. The author comes right out and tells you the information.
When they say "The cello has four strings that lie across the bridge piece; it does not have marked frets," they're directly implying the cello is a hard instrument to play.
Hoped I helped you!
Good luck on whatever you're doing!
