Allyl halides occur when the halogen atom is bonded to an sp³-hybridised carbon atom adjacent to an allylic carbon, that is, a carbon-carbon double bond.

Aryl halides are formed when the halogen atom is bonded directly to the sp²-hybridised carbon atom of an aromatic ring.

Vinylic bonds are formed when the halogen atom is bonded to an sp²-hybridised carbon atom of a carbon-carbon double bond. Simply put, it is the ethylene molecule with one of the hydrogen atoms replaced by another –R group.

Secondary bonds occur when the halogen is bound to a secondary carbon atom in the molecule. In the given molecule, the –Br is attached to a tertiary carbon atom which is in turn attached an sp³-hybridised carbon-carbon double bond. Hence this –Br is in an allylic position. Option (i) is correct.
