To answer this question, you need to understand the order of precedence for logical operators.
The correct answer is A) NOT.
The NOT operator is evaluated first because it has the highest precedence among the given options. The NOT operator is used to negate the value of a boolean expression. It takes a single operand and returns the opposite boolean value.
After the NOT operator, the order of precedence for the other logical operators is as follows:
B) AND - The AND operator is evaluated after the NOT operator. It returns true only if both operands are true.
C) XOR - The XOR (exclusive OR) operator is evaluated after the AND operator. It returns true if exactly one of the operands is true, but not both.
D) OR - The OR operator is evaluated after the XOR operator. It returns true if at least one of the operands is true.
E) They are always evaluated left-to-right - This option is incorrect because logical operators have a specific order of precedence.
Therefore, the correct answer is A) NOT. It is evaluated first among the given options.
