    Correct Answer:

    C

    Step-by-Step Solution

    Key idea: This is a systematic counting question on a matrix, recognisable because it provides a grid of numerical values and asks for the count of cells satisfying a specific inequality condition.

    Step 1: Identify the condition. We need to count cells where the pixel intensity U \leq 4.

    Step 2: Examine each row systematically.

    • Row 1: 0, 1, 0, 2 (All 4 values are \leq 4) -> Count = 4
    • Row 2: 4, 7, 3, 3 (4, 3, 3 are \leq 4) -> Count = 3
    • Row 3: 5, 5, 4, 4 (4, 4 are \leq 4) -> Count = 2
    • Row 4: 6, 7, 3, 2 (3, 2 are \leq 4) -> Count = 2

    Step 3: Sum the counts. Total = 4 + 3 + 2 + 2 = 11.

    Answer: C
