I will give brainliest if you answer this
nirvana33 [79]

Answer:

The answer is C

Step-by-step explanation:

It obviously can’t be 90° so you can cross B out.

And when you rotate 180° you change both of the signs so since A for example is like this (x,-y) it would be (-x,y)

Then it ends up to the left of where it needs to be so you have to move to the right.

Hope it all made sense! (:
