$\rule {100}{1.00}$

Answer 2

Option C is correct.

Step-by-step explanation:

∠ C A E = 70°

∠ B A F = 50°

∠ B A C = 180 - ( 70 + 50 )

∠ B A C =  60°

∠ B A F = ∠ C B A = 50° ( alternate angles )

∠ C A E = ∠ B C A = 70° ( alternate angles )

Thus ∠ B = 50°

And ∠ C = 70°

These are the values of the angles B & C.

Thus option C is correct.
