It is given in the question that,

where,

AB = 5 cm

FD = 5 cm

∠ B = 40°

∠ A = 80°

We know that sum of all angles of a triangle is equal to 180⁰

∴ ∠ A + ∠ B + ∠ C = 180^o

80^o + 40^o + ∠ C = 180^o

∠ C = 180^o - 120⁰

= 60^o

As, Angle C = Angle E

∴ Angle E = 60^o

Hence, option (B) is correct
