Expert Solution
Explanation
Here we have a && b ^ c. Now this expression will be evaluated with b^c as first, as we have XOR symbol used so the result of b^c will be true as b is false and c is true, and we know that XOR(^) returns true if both the operands are opposite of each other.
Now we have a && true, which will return true as we have AND(&) operator and it returns true when both the operand are true.
So here the overall expression is:
a && b ^ c
(true && (false ^ true))
true && true
true.
