    Option D is correct.

    Step-by-step explanation:

    We have to solve an equation with absolute value function.

    The equation is |x| - 1 - 10 = 0

    ⇒ |x| = 11

    ⇒ x = 11 or - 11 (Answer)

    This is because |x| gives the absolute value of any value of x.

    The definition of |x| can be given as

    |x| = x, when x ≥ 0 and |x| = - x, when x < 0.
