Explanation:
Detailed explanation-1: -A statement is true if what it asserts is the case, and it is false if what it asserts is not the case. For instance, the statement “The trains are always late” is only true if what it describes is the case, i.e., if it is actually the case that the trains are always late.
Detailed explanation-2: -A tautology is a formula which is “always true” that is, it is true for every assignment of truth values to its simple components.
Detailed explanation-3: -A variable cannot be subtracted. A variable represents a quantity. so X is representing a quantity which is 1. So the statement is TRUE.
Detailed explanation-4: -’Where are you going’ is not a statement.
