Attempt This Question
Not attemptedCorrect Answer: (a) 1 only
Hydrogels are routinely used for controlled drug-delivery/wound-dressing systems in patients (statement 1 correct). Their practical use in mobile air-conditioning or in the formulation of industrial lubricants is still at an R&D/concept stage, not an established application, so statements 2 and 3 are incorrect. Therefore only one statement is correct. ([upscfactory.in](https://upscfactory.in/q-in-which-of-the-following-are-hydrogels-used/?utm_source=openai))
