Good for them ! They worked with things that are related to math
and arithmetic, they had some fun, and they learned something.
Much better than just fishing for answers on some boring website.
Let the larger number be w and the smaller number be k;
5w-11=3k
3k+16=4w
Reorganizing the equations;
5w-3k=11
4w-3k=16
Subtracting equation 2 from equation 1:
w=-5
Replacing value of w in equation 1;
5(-5)-11=3k
-25-11=3k
3k=-36
k=-12
The numbers are -5 and -12
ANSWER

EXPLANATION
We want to simplify the expression,

Let us expand the bracket to obtain,

We now group the complex number parts and real number parts.

We simplify further to obtain,

This is in the form,

where

and
B. 11
Although eleven is a prime number, it's two factors (1 and 11) are odd integers
Answer: the answer is “B”
