Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) True true true false - This option is correct because it matches the output of the given code.

Option B) True true true true - This option is incorrect because the last statement (s3==s4) should evaluate to false. Although the content of the two strings is the same, they are created using the new keyword, which creates two different objects in memory. Therefore, the equality check using == returns false.

Option C) True false true false - This option is incorrect because the second statement (s1==s2) should evaluate to true. Since both s1 and s2 are initialized with the same string literal "Amit", they point to the same object in memory.

Option D) False false true false - This option is incorrect because the first statement (s1.equals(s2)) should evaluate to true. The equals() method compares the content of the strings, and since s1 and s2 contain the same value "Amit", the comparison returns true.

The correct answer is option A.
