AIIMS 2019 Chemistry Carboxylic Acids and Derivatives MCQ Question

Option B is correct because the compound in the diagram is classified as an analgesic, which is a substance that alleviates pain by acting on the central nervous system or peripheral tissues. Analgesics, such as acetaminophen (paracetamol) or non-steroidal anti-inflammatory drugs (NSAIDs), function by inhibiting the synthesis of prostaglandins, thereby reducing the perception of pain.

Option A, an anti-inflammatory compound, specifically targets inflammation rather than pain relief, while option C, a hypnotic, is designed to induce sleep rather than alleviate pain. Option D, an antiseptic, is used to prevent infection by killing or inhibiting the growth of microorganisms, which is unrelated to pain management.
