    B.

    Step-by-step explanation:

    Multiplicative inverse of a number is the number that completes the number to '1' when multiplied therefore the multiplicative inverse of - 7 is - 1/7

    Additive inverse of a number is the number that completes the number to '0' when added therefore the additive inverse of - 7 is 7
