The correct answer is: Orange

Resistance using the colour codes is written as 
R=[(numbers)×(multiplier) ±(tolerance(%))].

Colour 1: First significant figure
Colour 2: Second significant figure
Colour 3: Decimal multiplier
Colour 4(or no colour): Tolerance

For the given case:

Resistance can be written as =22×103±5% Ω.

Colour of the third band corresponds to decimal multiplier which is 103, hence colour is Orange.
