Step-by-step explanation:

Alright, lets get started.

We know the identity, even/odd

cos(-Θ) = cos (Θ)

Means cos(Θ)= $\frac{4}{5}$

Using triangle method and SOH CAH TOA, please refer the diagram attached

sin(θ)= $\frac{3}{5}$

We know, sin(-Θ)= -sin(Θ)

So, sin (-Θ) = $-\frac{3}{5}$

So the answer is C : Answer
