Which one of the following operators computes the remainder of an integer division?

The operator that computes the remainder of an integer division is the modulus operator, represented by the symbol %. This operator takes two integers as operands and returns the remainder that results from dividing the first operand by the second.

For instance, if you have the expression 7 % 3, the operation will divide 7 by 3, resulting in 2 with a remainder of 1. Thus, 7 % 3 evaluates to 1, which is the remainder of that division.

The other operators mentioned serve different purposes: A (/) is the division operator that performs standard division, producing a quotient; C () is typically not recognized as a standard operator for either division or modulus in most programming languages; and D (!) is commonly used as a logical NOT operator or a factorial operator depending on the context but does not apply to division operations.

Hence, the modulus operator % is the correct operator for computing the remainder of integer division.
