Valye of (x && y) can be true or false.
if (x && y) is true then !(x && y) is false. Which makes given statement (x && y) || !(x && y) = true.
if (x && y) is false then !(x && y) is true. Which makes given statement (x && y) || !(x && y) = true.
Hence value of given boolean statement is always true.
So option A is correct.
