Which of the following groups acts as both $-I$ effect and $o, p$-directing group?

Which of the following reactions yields biphenyl from chlorobenzene?

The major product of the reaction is:

Given below are two statements:
Statement $I$: Benzene is nitrated to give nitrobenzene,which on further treatment with $CH_{3}COCl / AlCl_{3}$ will give the product shown in the image.
Statement $II$: $NO_{2}$ group is a $m$-directing and deactivating group.
In the light of the above statements,choose the most appropriate answer:

The above reaction requires which of the following reaction conditions?

Two benzyne intermediates are likely to be formed equally. Reaction with amide ion can occur in two different directions with each benzyne,giving three possible products. They are formed in a $1 : 2 : 1$ ratio. Asterisk $(*)$ refers to $^{14}C$. Product $(A)$ is:
