• A. Negative
• B. Positive
• C. 0
• D. None of these

Answer 1

Answer: (A)

Negative

We know that the product of two integers with unlike signs (two integers, one with positive sign and one with negative sign) is always negative.

The given two integers are $-231$ and $+9$ and the product of these integers is:

$(-231)\times (+9)=-(231\times 9)=-2079$ which is a negative integer.

Hence, sign of the product of the given integers is negative.
