I'll be glad to check your answer.

Is it b

Right. Since there are 180 degrees in a triangle, this must be an equilateral.

Sum of angle in triangle=180°
180°=60°+60°+third angle
180°=120°+third angle
third angle=180°120°=60°
Equilateral triangle has three angles equal 60°
You triangle is equilateral triangle.
