Correct Answer

Explanation

The && operator in JavaScript performs a logical AND operation on its operands.
If both operands are truthy, the result is true, otherwise the result is false.
In this case, the first operand (x) is truthy (true), but the second operand (y) is falsy (false), so the result of the && operation is false.
