Detailed analysis:
We observe a Rubik’s Cube type cube with three visible faces:
Top surface: white
Left side: blue
Right side: pink
The missing piece is located in the inner corner where the three faces meet.
Step 1: Identify the colors of the missing piece.
A piece located in a corner always has 3 colors.
Since the missing piece is located at the intersection:
of the white (top) side,
of the blue (left) side,
of the pink (right) side,
It must contain these three colors:
White
Blue
Pink
All three options A, B, and C have these colors. Therefore, their orientation must be checked.
