Mesomeric effect involves

Which of the following statements are correct?
$(i)$ Inductive effect and resonance effect are possible in chlorobenzene.
$(ii)$ Resonance effect dominates over inductive effect in anisole.
$(iii)$ $p-$nitrobenzoic acid is less acidic than $m-$nitrobenzoic acid.
$(iv)$ Diphenylamine is more basic than aniline.

$x =$ number of compounds that are better hydride donors than $Ph-CH(O^{\Theta})_2$.

Which of the following can show hyperconjugation?

Match List-$I$ with List-$II$:
| List-$I$ (Mechanism steps) | List-$II$ (Effect) |
| :--- | :--- |
| $(A)$ Aniline resonance structure | $(I)$ $-E$ effect |
| $(B)$ Electrophilic addition of $H^+$ to alkene | $(II)$ $-R$ effect |
| $(C)$ Nucleophilic addition of $CN^-$ to alkene | $(III)$ $+E$ effect |
| $(D)$ Nitrobenzene resonance structure | $(IV)$ $+R$ effect |
