I think the answer is C.

Since the average is 30, the sum of the four +ve integers is 120.

(1) is not sufficient.

Given (2), 120 - 19 = 101. To get 101, u can have combination of 1 + 100 or 50 + 51. So u cannot determine the answer.

Given (1) and (2), u can say for sure that there are 2 integers greater than 30.
