Select the correct mirror image of the given figure when the mirror is placed…

Concept

A vertical mirror reverses left and right while preserving top–bottom positions and the overall orientation of a figure.

Each boundary, subdivision, and shaded region therefore appears at the same height and the same distance from the mirror, but on the opposite side.

Application

1. The original triangle points upward, so its reflected image must also point upward.

2. The shaded region in the upper-right interior moves to the upper-left interior.

3. The shaded region in the lower-left interior moves to the lower-right interior, and every internal line is reversed horizontally.

Cross-check

Reflecting the candidate back across a vertical line restores the original upper-right and lower-left shaded positions while keeping the apex at the top.

Therefore, the upward-pointing figure with shaded regions in the upper-left and lower-right interiors is the required mirror image.
