Coefficient of mutual inductance M=\\dfrac { { \\mu }_{ 0 }{ l }_{ 0 } }{ \\pi } emf=\\left| -M\\dfrac { dI }{ dt } \\right| =\\dfrac { { \\mu }_{ 0 }{ l }_{ 0 } }{ \\pi } 10=\\dfrac { { \\mu }_{ 0 } }{ \\pi }\\ volt As per lenz's law, the loop must move away. Hence there must be repulsive force.Answer is option A and C.
