Given below are two statements:
Statement I: Benzene is nitrated to give nitrobenzene, which on further treatment with 
will give
Statement II: 
group is a 
-directing, and deactivating group.
In the light of the above statements, choose the most appropriate answer from the options given below

Statement I: Benzene reacts with nitrating mixture (conc. 
conc. 
) to form nitrobenzene. However, nitrobenzene is highly deactivated due to the strong electron-withdrawing 
and 
effects of the 
group. Friedel-Crafts reactions (alkylation or acylation) do not occur on strongly deactivated rings like nitrobenzene. Thus, nitrobenzene will not react with 
to give m-nitroacetophenone. Statement I is incorrect.
Statement II: The 
group is a meta-directing group because it withdraws electron density from the ortho and para positions more than from the meta position. It is also a deactivating group as it reduces the overall electron density of the benzene ring, making it less reactive towards electrophilic aromatic substitution. Statement II is correct.
Therefore, Statement I is incorrect but Statement II is correct.
