Detailed Solution

Concept- According to the problem, I need to find the sum of this integer and its reciprocal. Therefore, we first need to understand the additive inversion of integers described below.
Reciprocal: The reciprocal of a number is a number that becomes zero or is equal to zero when added to an integer, and this number is also called opposite, sign inversion, and negation, and in the case of a real number, the sign is inverted. The opposite of a positive number or an integer is negative, and the opposite of a negative number is positive.
The sum of the integer and its reciprocal is always 0. This is because the sum of all integers a and their reciprocals (-a) is

Hence, the correct option is 3.
