The answer is A.
22000 +-5%.
Ans= 22000.
22000 +-5%.
Ans= 22000.

Red ---- Red ---- Orange ---- gold.
2 ---- 2 ---- 3 zeros ---- 5% tolerance.
So,
22000 +-5%.
Ans= 22000.
2 ---- 2 ---- 3 zeros ---- 5% tolerance.
So,
22000 +-5%.
Ans= 22000.

Nominal value means nothing if our resistor value 3 digits means tolerance value 5 % , 4 digits means tolerance value 1%.
Red-2,red -2,orange 10^3,
=22*10^3,
=22000.
Nominal value is 1% ,bcoz resistor value is 4 digits.
The resistor value is 22000.
Red-2,red -2,orange 10^3,
=22*10^3,
=22000.
Nominal value is 1% ,bcoz resistor value is 4 digits.
The resistor value is 22000.

(First color code * 10 + Second color code) * 10^(Third color code) +/- (gold[5%] / silver[10%] / no color[20%]).
