Answer:

The answer to your question is: letter C

Step-by-step explanation:

Multiplicative inverse is a pair of numbers which product gives 1.

Then

x will be our number

                     -9x = 1

                        x = - 1/9

because

                    -9 x  \frac{-1}{9} = \frac{9}{9} = 1
