The reaction with phenol is carried out the alkaline medium only (i.e., with phenoxide ion). The alkaline medium in 2 is not given.

Here 1, 3 and 4 reactions are possible.
$1 . A r {\overset{+}{N}}_{2} + C u B r \to A r B r + N_{2}$
$3 . A r {\overset{+}{N}}_{2} + H_{3} P O_{2} \overset{H_{2} O}{\to} A r H + H_{3} P O_{3} + N_{2}$
$4 . A r {\overset{+}{N}}_{2} + I^{-} \to A r I + N_{2}$
