Solution
The correct option is C13∘ Construction: Draw a line XY such that XY||BE||CF and is passing through O.
So, BE||XY and AO is the transversal. ⇒∠BOY=∠ABE (Corresponding angles are equal.) ⇒∠BOY=4x
Similarly, CF||XY and CO is the transversal. ⇒∠COY=∠DCF (Since corresponding angles are equal) ⇒∠COY=6x
