An invalid statement refers to a statement that is not mathematically or logically correct. In this case, both options A and B are correct because they are inequalities that can be true or false depending on the value of x. Option C is a valid statement because x can have a specific value, which is 1. On the other hand, option D is an invalid statement because x cannot have a value of 0 since it is undefined in math and can lead to undefined results when used in equations.
