Answer: Fourth option is correct.
Step-by-step explanation:
We need to find the pair of angles share ray FA as a common side.
DFA and DAB
We can see that DAB has no ray FA.
So, they can't share ray FA as a common side.
Similarly,
EFA and CAE
We can see that CAE has no ray FA.
So, they can't share ray FA as a common side.
Similarly,
BFA and EAD
We can see that EAD has no ray FA.
So, they can't share ray FA as a common side.
Finally,
BFA and FAD
Both the angles have FA as a common ray.
So, they can share FA as a common side.
Hence. Fourth option is correct.
