Show answer and explanation

Correct answer: (A) Option A in the figure

Explanation

Viewed along the arrow, the lower block projects as an unbroken rectangle and the upper block has its sloping edge on the left. This is option A. B incorrectly continues a diagonal through the lower block; C reverses the sloping side; D omits the raised block’s silhouette and introduces an internal diagonal. The selected view must preserve both the outline and the visible edges.
