A deuteron with a binding energy \( E_B \) can be dissociated into a proton and a neutron by absorbing a gamma-ray photon with energy \( E \). Which of the following statements is correct?
1
\( E \) should be less than \( E_B \)
2
\( E \) should be exactly equal to \( E_B \)
3
\( E \) does not depend on \( E_B \)
4
\( E \) should be more than \( E_B \)
