In H-molecule two nucleus of 2 H-atoms are separated by the order of angstrom, which means nuclear forces will exist and hence electron wouldn’t move in circular orbits. So option (a) is correct. Now in ground state energy of H-atom will be in accordance with Bohr calculation so option (b) is wrong, now we know one electron and two protons are there so electron will revolve around protons so option (c) is correct and obviously (d) option is wrong.

Therefore option (a) & (c) are correct.
