A wire carries a current. Maintaining the same current it is bent

A wire carries a current. Maintaining the same current it is bent first to form a circular plane coil of one turn which produces a magnetic field B at the centre of the coil. The same length is now bent more sharply to give a double loop of smaller radius. The magnetic field at the centre of the double loop, caused by the same current is (a) 4B (c) B/2 (b) B/4 (d) 2B
