Answer is right were we have to add max resistance i.e. 120000+5% = 126000 ohms.

First two colors are digits: Brown-1 & red -2.
Third color yellow is multiplier: Yellow -10000.
Last color is tolerance: Gold- 5%.
(12*10000)+/_(5% of 120000) = 126000 (max).
Third color yellow is multiplier: Yellow -10000.
Last color is tolerance: Gold- 5%.
(12*10000)+/_(5% of 120000) = 126000 (max).

Wrong answer.
Answer is according to resistor color code.
B B R O Y Great Britain Very Good Wife.
It shows black, brown, red, orange, yellow, green, blue, violet, grey, and white in 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 respectively.
That's why resistance is 120000.
And tolerance of gold is 5%.
So it become 120000+6000 = 126000.

What about Tolerance codes? Every tolerance is 5.

1 comes for brown;2 comes for red;10^4 comes for yellow so we get 12*10^4=120000.

Brown = 1.
Red = 2.
Yellow = 10^4.
12 x 10000 = 12000.
Ol = + or - 5 tolerance.
12000 x .05 = 6000.
12000+6000 = 126000.
Ans: A.
Red = 2.
Yellow = 10^4.
12 x 10000 = 12000.
Ol = + or - 5 tolerance.
12000 x .05 = 6000.
12000+6000 = 126000.
Ans: A.

Why gold tolerance is 5%?
