pe, size, and position.

Step by step
Step 1: Identify the four hole shapes and their spatial arrangement in the socket.
Step 2: For each plug option, check if the number, shapes, sizes, and orientations of the pins match the socket holes exactly.
Step 3: Option A — pins match the socket holes in shape and arrangement. ✓
Step 4: Option B — one or more pins are the wrong shape or orientation. ✗
Step 5: Option C — pin arrangement or sizes do not match. ✗
Step 6: Option D — pins match the socket (possibly viewed from a different angle). ✓
Therefore the answer is A and D.

Why wrong options are wrong
Option B: A pin shape or orientation does not correspond to the available holes.
Option C: The pin configuration is incompatible with the socket hole layout.

Remember for exam
For plug-socket questions, check each pin individually against its corresponding hole — one mismatch disqualifies the whole plug.
