The maximum energy is posessed by an electron when it is present ina.nucleusb.ground statec.first excited stated.infinite distance from nucleus

@ sneha 
option no 3 turns out to be the correct option , as in ground state it cannot have maximum energy beacuse its bound by the nucleaus , 
and in frst exited state it will have maximum energy as when it will gain some energy , only then it will able to go to the first excited state . 
and infinity distance is not possible in the case of electron . 
HOPE IT CLEARS 

ALL THE BEST ..
