• A

∠ BCD – ∠ BAD  • B

∠ BAD + ∠ BCF  • C

∠ BAD + ∠ BCD  • D

∠ CBA + ∠ ADC  • Option : A
• Explanation : ∠E + ∠F = ?
α + q + E = 180       ...(i)
α + β + F = 180       ...(ii)
α + β + p + q = 360       ...(iii)
Equation (i) + (ii) = (iii)
α + q + E + α + β + F = α + β + p + q
E + F = p - α

• A
