The regioselectivity in the nitration of acetanilide is due to the directing effect of the amino group (-NH2) in the molecule. The amino group directs the nitration primarily to the meta position on the aromatic ring, resulting in the formation of meta-nitroacetanilide as the main product.
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).

We can not give you an answer as you do not give a choice. However, cells stay small because they are the right size to function properly. Perhaps you can select an answer from that.

nitration of the benzene ring and gives positive
Aromatic amines cannot be nitrated directly because they give unexpected oxidation products along with nitration products. This is because, HNO3 is not only a nitrating agent but also acts as a strong oxidizing agent. Therefore, to solve this problem, nitration is carried out by protecting the -NH2 group by acetylation. The acetyl group is finally removed by hydrolysis to give a mixture of o- and p-nitro amines.
Nitrobenzene is typically synthesized by nitration of benzene using a mixture of concentrated nitric acid and sulfuric acid as the nitrating agents. The reaction involves the substitution of a hydrogen atom on the benzene ring with a nitro group, resulting in the formation of nitrobenzene.
H2SO4 is necessary in the preparation of nitrobenzene because it acts as a catalyst in the nitration reaction. It helps in activating the nitric acid to facilitate the nitration of benzene to form nitrobenzene. Additionally, H2SO4 helps in maintaining the acidic conditions required for the reaction to proceed efficiently.

If there was no reason then obviously it is impossible to give a reason why.
