c, because Oxygen likes to stick together

its (c)
reason:
He cannot form double bond it is a inert gas .oxy has 8e- .its valence e- is 6.it need 2e- to complete its octet so it can share 2e- with other other oxygen .nitrogen has 9e-.it has 7e- in the valence shell.so it cannot form double bond to completes its octet.even cl does not make double bond because of this reason.

yeah, oxygen has 8 electrons, 6 in its outer shell, this means that it needs to gain 2 electrons, so each atom shares 2 electrons with the other
