Answer:

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.
