Since we know module could be solved as either positive or negative value.
Case 1: |X-2|=2|X-2|
X-2 = 2(x-2) Both positive
X=2
Case 2: |X-2|=2|X-2|
X-2 = 2*-(x-2) L.H.S positive, R.H.S. negative
X=2
Case 3: |X-2|=2|X-2|
-(X-2) = 2*-(x-2) Both negative
X=2
Case 4: |X-2|=2|X-2|
-(X-2) = 2*(x-2) L.H.S negative, R.H.S. positive
X=2
So no matter what. X value is coming down to 2.
So OA is C
