answer : answer option (c) 1 volt

explanation : we know, induced emf on self inductance is given by, \xi=L\frac{d\iota}{dt}

where \xi denotes induced emf on self inductance, L is self inductance and \frac{d\iota}{dt} is the rate of change of current with respect to time.

here, L=5H, \frac{d\iota}{dt}=\frac{2-1}{5}=\frac{1}{5}

hence, \xi = 5 × 1/5 = 1 volt

hence, answer is option (c)
