Method prototype for the method compute which accepts two integer arguments and returns true/false.

boolean compute (int a, int b)

Reason — Let's analyse the given options:

1. void compute (int a, int b) — Incorrect because void means the method does not return any value, but the question requires the method to return true/false.

2. boolean compute (int a, int b) — Correct because it returns a boolean value (true or false) and accepts two integer arguments.

3. Boolean compute (int a, b) — Incorrect due to syntax error (int b is not fully declared). Also, Boolean is a wrapper class, not a primitive boolean.

4. int compute (int a, int b) — Incorrect because the return type is int, not boolean.
