Given the absolute value, we have to evaluate it for x >= 0 and for x <0.
If x >= 0, we get x+1 = x-1, 1 = -1 impossible
If x < 0, we get x+1 = 1-x, x= 0.
Thus, the answer is C
If x >= 0, we get x+1 = x-1, 1 = -1 impossible
If x < 0, we get x+1 = 1-x, x= 0.
Thus, the answer is C

Given that,
x + 1 = |x - 1|
So,
Either,
x + 1 = x - 1 or x + 1 = - (x - 1)
here x undefined here x = 0
Thus, the above equation satisfy only when x = 0
Hence, Choice C answer.
