Answer:
(A) Always true
<em></em>
Explanation:
Given
Boolean variables x and y
Required
What is (x && y) || !(x && y)
Irrespective of what x or y is, the x && y is always true
Take for instance:
<em>x = true;</em>
<em>y = true;</em>
<em>x&&y will also be true because the values of x and y were not altered</em>
<em />
<em>And this is true for whatever boolean value x or y assume</em>
<em />
Having said that:
x&&y = true
So, the expression is analysed as follows:
(x && y) || !(x && y)
Substitute true for x&&y
(true) || !(true)
<em>!(true) = false</em>
So, the expression becomes:
true || false
|| represents the OR operator; and it returns true if at least one of the conditions is true.
By this:
true || false = true
<em>Option (A) Always true </em><em>answers the question.</em>
