A Correct answer
Explanation

Volume of a prism = base area × height (lateral edge). If base remains same and lateral edges are halved, new volume = base area × (height/2) = (base area × height)/2 = original volume/2. Reduction = (original - new)/original = 50%. The volume is directly proportional to height.
