उत्तर
O2
Explanation:
Oxygen (O2) is paramagnetic because it has two unpaired electrons in its molecular orbital configuration. The presence of unpaired electrons causes it to be attracted by a magnetic field. In contrast, N2, H2, and Li2 molecules have all their electrons paired, making them diamagnetic (not attracted by a magnetic field).
