The correct option is B Gandhinagar
Several cities serve as industrial hubs of the country. These are cities like Coimbatore in Tamil Nadu, which are famous for textile industries, Hooghly in West Bengal famous for Jute and several other large and small-scale industries. Raigarh in Chhattisgarh is known for its steel industries and power plants. Gandhinagar is the odd one out as it is not an industrial hub.
