Difficult terrain and poor connectivity in some parts of Assam hinder:

The correct answer is: All of the above.

Difficult terrain and poor connectivity in some parts of Assam hinder access to healthcare services, delivery of essential medicines, and disease surveillance.

• Access to healthcare services is hindered by the lack of roads and bridges, which makes it difficult for people to reach hospitals and clinics. In addition, many remote areas do not have any healthcare facilities at all.
• Delivery of essential medicines is also hampered by the poor infrastructure. Medicines often have to be transported over long distances, which can lead to delays and shortages. In addition, the cost of transportation can be high, making it difficult for people to afford the medicines they need.
• Disease surveillance is also difficult in remote areas. This is because there are often no health workers in these areas, and it can be difficult to get information about diseases. In addition, the lack of roads and bridges makes it difficult to reach people who are sick.

All of these factors contribute to the poor health of people in remote areas of Assam.
