Answer:

The answer is D: di nitrogen tetr oxide

Explanation:

Since nitrogen has many oxides, we need to specify them by using number-prefixes for both nitrogen and oxygen. Usually (but not allways) the mono- (=one)-prefix is omitted.

The nitrogen oxides are:
(the piece between brackets is sometimes omitted)
#N_2O# dinitrogen monoxide
#NO# nitrogen (mon)oxide
#N_2O_3# (di)nitrogen trioxide
#NO_2# nitrogen dioxide
#N_2O_4# (di)nitrogen tetroxide
#N_2O_5# (di)nitrogen pentoxide

#N_2O_4# does not usually occur as a pure substance, as it is in a dynamic equilibrium with #NO_2#:

#N_2O_4harr2NO_2#
