Correct Answer

The correct answer is:

Explanation:

int a = Integer.parseInt(P); - Converts the string "20" to an integer and assigns it to variable a.
int b = Integer.valueOf(Q); - Converts the string "22" to an integer and assigns it to variable b.
System.out.println(a + "" + b); - Concatenates the values of a and b as strings and prints the result. In this case, it prints "20" + "22", resulting in "2022".
