The question is which figure shows ∠ POQ.
The answer is the option A.
Justification:
The notation ∠ POQ means angle POQ. And that means:
1) the vertex of the angle is the point O (this is the letter at the center of the name).
2) The sense of the measure is from P to Q counter clockwise.
That is what the figure A shows.
The figue B shows ∠ OQP, the figure C shows ∠QPR, and the figure D shows ∠QRP
