If $$a_{1} , a_{2} . .. .. a_{40}$$ are in arithmetic progression, then the common difference is
(I) $$a_{36} - a_{10} = 52$$
(II) $$a_{40} = 83$$

A

if the statement I alone is sufficient to answer the question.

B

if the statement II alone is sufficient to answer the question.

C

if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient
