Expert Answer:

Energy can be calulated by-
E equals negative 13.6 Z squared over n squared
I n space o p t i o n space left parenthesis 1 right parenthesis comma space increment E equals E subscript 2 minus E subscript 1
space increment E equals negative fraction numerator 13.6 over denominator 4 end fraction minus open parentheses negative fraction numerator 13.6 over denominator 1 end fraction close parentheses equals 10.2 space e V

I n space o p t i o n space left parenthesis 2 right parenthesis comma space increment E equals negative fraction numerator 13.6 over denominator 9 end fraction minus open parentheses negative fraction numerator 13.6 over denominator 4 end fraction close parentheses equals 1.59 space e V

I n space o p t i o n space left parenthesis 3 right parenthesis comma space increment E equals fraction numerator negative 13.6 over denominator 1 end fraction minus open parentheses fraction numerator negative 13.6 over denominator infinity end fraction close parentheses equals negative 13.6 space e V

I n space o p t i o n space left parenthesis 4 right parenthesis comma space increment E equals negative fraction numerator 13.6 over denominator 25 end fraction minus open parentheses fraction numerator negative 13.6 over denominator 9 end fraction close parentheses equals 0.0962 space e V

S o comma space c o r r e c t space o p t i o n space i s space left parenthesis A right parenthesis
