Answer:
∠3 and ∠6 forms alternate interior angle .
Option (B) is correct .
Step-by-step explanation:
Definition of alternate interior angle
A pair of angles on the inner side of each of two parallel lines but on opposite sides of the transversal.
As given in the figure
a and b are the parallel lines and c is the transversal .
Thus ∠3 and ∠6 are made is the inner side of each of parallel lines a and b intersect by transversal c .
Thus
∠3 and ∠6 forms alternate interior angle .
Option (B) is correct .
