Binding Energy

when two nuclei (A lt= 10) fuse together to form a heavier nucleus, the (a) binding energy per nucleon increases (b) binding energy per nucleon decreases (c) binding energy per nucleon does not change (d) total binding energy decreases

Statement-1:In a nuclear reaction energy is released , if total binding energy is increasing. Statement-2:For a stability of a nucleus, total binding energy is more important than binding energy per nucleon. Statement-3:Nuclear force is different for different nucleons and it dependent on charge .
