(1) n = 8
(2) The square of the number of integers in the list is 64
Each statement indicates the same information -- that there are 8 odd integers.
Thus, both statements are satisfied by the following cases:
Case 1: 1, 1, 1, 1, 1, 1, 1, 1
Case 2: 1, 1, 1, 1, 1, 1, 1, 3
In Case 1, the sum of the 8 odd integers = 8.
In Case 2, the sum of the 8 odd integers = 10.
Since the sum can be different values, the two statements combined are INSUFFICIENT.

The correct answer is E.
