The correct option is 1, 2, and 3 only, as these reflect the roles of ASHA (Accredited Social Health Activist) within the National Rural Health Mission. ASHAs are primarily tasked with promoting maternal and child health, which includes accompanying pregnant women for antenatal check-ups (1), using pregnancy test kits for early detection (2), and providing critical information on nutrition and immunization (3). However, conducting deliveries (4) is not within their scope of practice, as this task is typically managed by trained health professionals. This delineation of duties underscores ASHAs' role in facilitating access to health services rather than providing clinical services themselves, aligning with community health strategies aimed at empowering local participants while ensuring professional healthcare is delivered appropriately.
