Answer / jayasree s
A complex Boolean condition by combining simple Boolean
conditions with the logical operators AND, OR, and NOT.
FALSE takes precedence in an AND condition and TRUE takes
precedence in an OR condition. AND returns TRUE only if
both of its operands are TRUE. OR returns FALSE only if
both of its operands are FALSE. NULL AND TRUE always
evaluate to NULL because it is not known if the second
operand evaluates to TRUE or not.
Note: The negation of NULL (NOT NULL) results in a null
value because null values are indeterminate
Answer is FALSE
