Both the statements give us the same information, so we can upfront eliminate A B C, either the answer is D or E.

Statement 1

n = 9

We know that n = 9, but with no other information provided, we don't know what those 9 integers are. Hence we cannot find the sum.

There is no need to evaluate statement 2.

Option E

(1) n = 9

The sum of 9 odd integers can be anything depending on the numbers
For ex:
Sum (1,3,5,7,9,11,13,15,17) = 81
Sum (3,5,7,9,11,13,15,17,19) = 99
Different results => NOT SUFFICIENT

(2) The square root of the number of integers on the list is 3.

This implies that Number of Integers on list = 9
The results are same as in Statement 1 discussed above:
Different results of sum of 9 odd integers based on the numbers in the list

NOT SUFFICIENT

Combined, both statements together say nothing new except what has already been mentioned in the 2 statements above (which both say the same thing as well)

NOT SUFFICIENT

Answer - E
