Explanations:Andhra Pradesh is a state in southern India that is known for its extensive coastline along the Bay of Bengal. The state is divided into several districts, each with its own unique geographical features. Understanding the layout of these districts is crucial for identifying which ones are coastal.
Coastal districts are those that have a direct border with the sea. In the case of Andhra Pradesh, the coastline is along the Bay of Bengal, which is a part of the Indian Ocean. The coastal districts of Andhra Pradesh include Visakhapatnam, East Godavari, West Godavari, Krishna, Guntur, Prakasam, and Nellore. These districts are characterized by their proximity to the sea, which influences their climate, economy, and culture.
Among the options provided, only Vishakhapatnam is a coastal district. It is located in the eastern part of Andhra Pradesh and is known for its port city, which is a significant economic and cultural center. The city of Vishakhapatnam is situated on the coast and is a major port, making it a key district in the state's coastal region.
The other options, Karnool, Ananthapur, and Chittur, are not coastal districts. Karnool is an inland district located in the central part of the state, while Ananthapur is an inland district in the western part of Andhra Pradesh. Chittur is not even a district in Andhra Pradesh; it is a village in Tamil Nadu, which is a neighboring state.
Therefore, the correct answer is Vishakhapatnam, as it is the only district among the options that lies on the coastline of Andhra Pradesh.
