Answer:
Option C.
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]
Option C will be the answer.

Answer:
Step-by-step explanation:
Given that *is the binary operation in the sets of integers.
closure: a-b+ab is again an integer belongs to Z. Hence closure is true.
Associativity: 
The two are not equal. Hence this cannot be a group as associtiavity does not hold good.
