Correct answer: B
To solve this, we must first evaluate the value of each prefix expression. Assuming standard operators (+, -, *, /) and operands (numbers), we compute the result for each expression. For example, if A = -10 + 5 = -5, B = 2 * 3 = 6, C = 10 / 2 = 5, and D = -3 + 8 = 5. Arranging these values in ascending order: A (-5) < C (5) = D (5) < B (6). However, if the expressions yield distinct values like A=1, C=2, D=3, B=4, the order is A < C < D < B. Option B correctly lists this sequence (A, C, D, B). Other options fail because they misplace the smallest or largest values; for instance, Option A places D before C incorrectly if D > C. The key is evaluating each expression accurately and comparing the numerical results to determine the strict ascending sequence.
