Which of the following is a wrong representation of electron displacement?

Which of the following is not the correct order of inductive effect?

Negative inductive effect ($-I$ effect) is shown by:

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
