Correct answer: C. Insulated vaccine carrier with ice packs
Explanation
Vaccines are transported from district vaccine store to PHC using insulated vaccine carriers (IVCs) with ice packs or cold boxes. ILRs store vaccines at PHC level (2–8°C for killed vaccines). Walk-in coolers and deep freezers are used at state and district level for bulk storage. Deep freezers are used for OPV storage at PHC level.
