we don't have enough information to determine the value of ∠3. (B)
Angle 2 + 96 = 180 ( Sum of angles on the same side of traversal is 180)
Angle 2 = 180 - 96
Angle 2 = 84°
Angle 1 + Angle 3 = 180 ( Sum of angles on the same side of traversal is 180)
However, we don't have enough information to determine the value of ∠3.
Hence, the correct option is B.
