$\text{Hint: Strong deactivating groups (like -NO}_2 \text{ and -NH}_2\text{) do not allow Friedel-Crafts alkylation or acylation.}$ $\text{Step 1: Friedel-Crafts Reaction Restrictions:}$ $\text{(1) Strong deactivators (like -NO}_2 \text{ and -NH}_2\text{) do not allow Friedel-Crafts alkylation or acylation due to their electron-withdrawing effects.}$ $\text{(2) Halogens (-Cl) are deactivating but still allow the Friedel-Crafts reaction because they are ortho/para directing.}$ $\text{(3) Alkyl group (-CH}_3\text{, -C}_2\text{H}_5\text{) are activating and favor Friedel-Crafts reaction.}$ $\text{Step 2: Friedel Crafts' reaction is given by}$ $\text{(i) Aniline (-NH}_2\text{ group) } \rightarrow \text{ Does NOT undergo Friedel-Crafts due to strong Lewis acid-base interaction with AlCl}_3\text{, which deactivates the ring.}$ $\text{(ii) Nitrobenzene (-NO}_2\text{ group) } \rightarrow \text{ does NOT undergo Friedel-Crafts due to strong deactivation.}$ $\text{(iii) m-Dinitrobenzene (-NO}_2\text{ groups) } \rightarrow \text{ Does NOT undergo Friedel-Crafts for the same reason as above.}$ $\text{(iv) p-Xylene (-CH}_3\text{ groups) } \rightarrow \text{ Undergoes Friedel-Crafts (activating group).}$ $\text{(v) Chlorobenzene (-Cl group) } \rightarrow \text{ Undergoes Friedel-Crafts (deactivating but still reactive).}$ $\text{(vi) p-Nitrochlorobenzene (-NO}_2\text{ and -Cl groups) } \rightarrow \text{ Does NOT undergo Friedel-Crafts due to strong deactivation by -NO}_2\text{.}$ $\text{(vii) Cumene } \rightarrow \text{ Undergoes Friedel-Crafts (activating group).}$ $\text{Out of the given compounds, only three will give Friedel-Crafts reaction. Hence, option 1 is the correct answer.}$
