With reference to India's defence, consider the following pairs : I. Dornier-228 : Maritime patrol aircraft II. IL-76 : Supersonic combat aircraft III. C-17 Globe-master III : Military transport aircraft How many of the pairs given above are correctly matched?

Lists Dornier DO-228 among Indian Airlines' fleet, showing the type exists in Indian civil aviation service.

A student could note that an aircraft type used civilly often has multiple variants (civil/military) and look up whether military versions or maritime variants of the DO-228 exist or are procured by defence services.

Explains Airport Authority of India operates both civil enclaves and defence airfields, indicating aircraft of a given type can be operated in civil or defence roles.

Combine this with knowledge of where Dornier-228s are based to check whether any are assigned to defence airfields (suggesting military/maritime use).

Describes India's extensive coastline and strategic maritime location, implying a practical need for maritime patrol capabilities.

Given the maritime security requirement, a student could investigate which small aircraft types (e.g., light turboprops like the DO-228) are typically used for maritime patrol and whether India equips DO-228s for that role.

Defines 'Defence of India' and explicitly lists naval, military and air forces, highlighting that maritime (naval) surveillance is a defence responsibility.

A student could use this to justify checking defence procurement records or service inventories (Navy/Coast Guard) for DO-228 maritime patrol variants.
