Option A is not correct because Boolean value cannot be 0 because it is a long value.

Option B is not correct.

Option D is not correct because there is no class Boolean.

Option E is not correct it should be "true" or "false".

Why A is not Correct? Answer me clearly.

Option A is not correct because in boolean data type it's consists only true or false statement.

Option B also not correct because false is declared within single quotes like string.

So, Option C is right.
