C.
Mr. White’s jealousy of Sergeant-Major Morris’s travels is revealed.

Answer 1

A. The mystery around the monkey's paw is introduced

Hints of this lie  in the adjectives such as "curiously" and the mention of "magic" which tells the reader that there might be something more to monkey's paw, and that maybe we should be curious.
