Question

I thought the answer is PTA but that isn't an option so I don't know, does anyone else have an idea and possibly an explanation?

Answer 1

The answer is APT!

Explanation:

The triangle is flipped, but is otherwise the same. So, wherever BRO is on the first triangle, APT will be on the second! I don't know if that explanation makes much sense, but I hope it helps haha.

Answer 2

APT

Explanation:

Make sure they are corresponding with each other so BRO in lefthand triangle corresponds with APT in the righthand one, therefore your answer is APT
