Answer:
option a
Step-by-step explanation:
2 lines are said to be parallel when they don't intersect each other & they won't meet each other if the distance ( which separates both the lines intersecting each other ) is perpendicular to both the lines.
Here in the figure AC is perpendicular to both AB & CD. Hence AB || CD. Taking BC as transversal , m(2) = m(4) = 35°
