Answer: C

Explanation:

Requirement:

Method name: compute
Accepts two integer arguments → (int a, int b)
Returns true/false → the return type should be boolean

Step 1: Check options

(a) void compute(int a, int b) → ❌ void means no return value

(b) boolean compute(int a, int b) → ✅ Correct, returns a primitive boolean

(c) Boolean compute(int a, int b) → ✅ Technically correct too, returns wrapper class Boolean, but usually we use boolean for primitives

(d) int compute(int a, int b) → ❌ Returns integer, not true/false

✅ Best Answer: (b) boolean compute(int a, int b)

Note: Option (c) is technically valid but primitive boolean is standard for such cases.
