    The answer is A.

    If a redundant conclusion is reached in basic algebra this states that the variable holds all possible real values.

    If you algebraically solve Kendra's you do achieve the true statement 5 = 5 (leaving out D). And if you test any value of x for the equation it does hold true (getting rid of B).

    Hopefully this makes sense.
