Given:
java
interface Calculable {
long calculate(int i);
}
public class Test {
public static void main(String[] args) {
Calculable c1 = i -> i + 1; // Line 1
Calculable c2 = i -> Long.valueOf(i); // Line 2
Calculable c3 = i -> { throw new ArithmeticException(); }; // Line 3
}
}
Which lines fail to compile?

• A. Line 2 and line 3
• B. Line 3 only
• C. Line 1 only
• D. The program successfully compiles
• E. Line 1 and line 3
• F. Line 1 and line 2
