Answer: Option D

Explanation:

x > 5 and y < -1, we can make the following conclusions:

x + y > 4: Since x is greater than 5 and y is less than -1, their sum will be greater than 4. Therefore, the statement "x + y > 4" is true.

x * y < -5: Since x is greater than 5 and y is less than -1, their product will be less than -5 (because a positive number multiplied by a negative number gives a negative result). Therefore, the statement "x * y < -5" is true.

Therefore, the true statement is "x + y > 4", and the statement "x * y < -5" is also true.

So , the correct Ans is None of these.
