Correct Answer: Option D

Explanation

In Java, the expression b >>= c is a compound assignment operator that performs a right shift on the variable b by the number of bits specified on the right side of the >>= operator. It is equivalent to the expression b = b >> c.

Here's an example in Java:


public class CompoundAssignmentExample {
    public static void main(String[] args) {
        // Declare variables
        int b = 12;
        int c = 2;

        // Compound assignment (right shift by 2 bits)
        b >>= c;

        // Display the result
        System.out.println("The value of b after b >>= c is: " + b);
    }
}

In this example, if b is initially 12, after the operation, the value of b will be 3. This is because the binary representation of 12 is 1100, and right-shifting it by 2 bits results in 0011, which is 3 in decimal.
