Solution

The correct option is D
$- a$

Correct option: d) $- a$
Let $a$ be an integer. then by the rule of multiplication of integer $a \times (- 1) = - a$
So, this is correct.
Incorrect options:
a) $a$
Since $a \times (- 1) = - a$
So, this is correct.
b) $1$
Since $a \times (- 1) = - a$
So, this is incorrect.
c) $- 1$
Since $a \times (- 1) = - a$
So, this is incorrect.
Hence, option (d) is correct.
