Answer showed wrong (Question: 121532.0 )

I gave the right one and according to solution provide, my answer is correct, but it still gave me the answer as incorrect

Question:
DIRECTION: What should come in place of the question mark (?) in the following question?


1 - [5 - {2 + (- 5 + 6 - 2) 2}] = ?       

Options:
A) -4
B) 2
C) 0
D) -2
E) None of these
Solution:

1 - [5 - {2 + (- 5 + 6 - 2) 2}]

= 1 - [5 - {2 + (-1) × 2}]

= 1 - [5 - {2 - (2)}]

= 1 - [5 - {2 - 2}]

= 1 – 5 – 0 = -4

because you will not have marked -4 as correct answer......-4 is correct answer..


1 - [5 - {2 + (- 5 + 6 - 2) 2}]
= 1 - [5 - {2 + (-1) × 2}]
= 1 - [5 - {2 - (2)}]
= 1 - [5 - {2 - 2}]
= 1 – 5 – 0 = -4
