OPTION B IS CORRECT ANSWER

IV > III > II > I is the trend of carboncation formation.
Explanation:
- The carboncation is a reaction intermediate that involves a positive charge on a carbon atom.
- This carboncation formation is effected by the stability of the carbocation.
- More stable carbocations are readily formed than the less stable ones.
- In case of the benzyl alcohol, its supported by resonance and the charge is widely dispersed in the molecule.
- So it will be highly preferred.
- In case of option 3, the carbocation is 2° where it's supported by positive inductive effect of the methyl groups.
- In case of option 1 and 2, both are rendered unstable by the negative inductive effect of the fluorine atoms.
- But the effect is rendered through 2 carbon atoms in option 2 and 1 carbon atom in carbon 1.
- So option 1 is more unstable than option 2.
- So the trend is IV > III > II > I.
