Answer:

b. [tex]\frac{1}{y^3}[/tex]

Step-by-step explanation:

Here we are given  [tex]y^{-3}[/tex] and are asked to simplify it. We are going to apply the law of exponents which says that

[tex]a^{-n}=\frac{1}{a^n}[/tex]

Hence applying this rule in our problem we get, where a=y and n=3

[tex]y^{-3}=\frac{1}{y^3}[/tex]

Hence our C) Option is correct
