  • A int a = 5; ✔ ✖
  • B if int a ✔ ✖
  • C int switch b; ✔ ✖
  • D int 5 = a; ✔ ✖
Correct Answer: Option A

Explanation

✅ A) int a = 5;

The statement int a = 5; is a correct and valid Java statement because it properly declares and initializes a variable.

Breakdown:

  • int → Data type
  • a → Variable name
  • = 5 → Assigns the value 5 to the variable
  • ; → Statement terminator in Java

Why the other options are incorrect:

  • ❌ if int a
    This is incomplete and does not follow proper Java syntax.
  • ❌ int switch b;
    The word switch is a reserved keyword in Java and cannot be used as a variable name.
  • ❌ int 5 = a;
    Variable names cannot start with numbers in Java.
