°, 180°, 270°) — no colour changes, no flipping of colour blocks.

Step by step
Step 1: Study the colour distribution on the single tile carefully — the proportions and positions of yellow, pink, red, and the small accent square.
Step 2: Option A — check each sub-tile unit against the original; all match valid rotations of the tile. ✓
Step 3: Option B — similarly consistent with rotated copies of the tile. ✓
Step 4: Option C — one or more sub-tile positions show a colour distribution that cannot be achieved by rotating the given tile. ✗
Step 5: Option D — colour proportions or positions are incompatible with any rotation of the tile. ✗
Therefore the answer is A and B.

Why wrong options are wrong
Option C: The colour block sizes or positions differ from those of the given tile even when rotated.
Option D: The pattern includes colour arrangements that require the tile to be modified, not just rotated.

Remember for exam
In tile pattern questions, isolate one tile from the pattern and compare it cell-by-cell with the original — a single mismatched colour block eliminates that option.
