The decreasing order of acidic nature of the following compounds is

Arrange the following compounds in decreasing order of reactivity towards $EAS$ (electrophilic aromatic substitution).

The most stable canonical structure among the given structures is:

Given below are two statements $:$
Statement $I :$ Hyperconjugation is not a permanent effect.
Statement $II :$ In general,greater the number of alkyl groups attached to a positively charged $C$ atom,greater is the hyperconjugation interaction and stabilization of the cation.
In the light of the above statements,choose the correct answer from the options given below
