A semicircular current carrying wire having radius R is placed in x-y plane with its center at origin ‘O’. There is non-uniform magnetic field vector B = (B0x/2R) cap k(here B0 is +ve constant) is existing in the region. The magnetic force acting on semicircular wire will be along
(A) –x-axis
(B) +y-axis
(C) –y-axis
(D) +x-axis
