(B) The induced emf $(e)$ in the secondary coil is given by the formula: $e = M \frac{di}{dt}$.Given:Mutual inductance $(M) = 92 \times 10^{-6} \, H$.Rate of change of current $(\frac{di}{dt}) = \frac{25 \, A}{1 \, ms} = \frac{25 \, A}{1 \times 10^{-3} \, s} = 25,000 \, A/s$.Substituting these values into the formula:$e = 92 \times 10^{-6} \times 25,000$$e = 92 \times 10^{-6} \times 25 \times 10^3$$e = 92 \times 25 \times 10^{-3}$$e = 2300 \times 10^{-3} = 2.3 \, V$.Therefore, the induced emf in the secondary coil is $2.3 \, V$.
