Answer:
The correct option is B. 60°
Explanation:
In ΔPCD and ΔPBA
PD = PA (radius of the same circle)
PC = PB (radius of teh same circle)
DC = AB (given)
So, By SSS congruency property of triangles,
ΔPCD ≅ ΔPBA
Now, By using CPCT property of two congruent triangles
m∠CPD = m∠BPA = 60°
⇒ x = 60°
Therefore, the correct option is B. 60°
