Consider the following pairs: Region Well-known for the production of 1. Kinnaur : Areca nut 2. Mewat : Mango 3. Coromandel : Soya bean Which of the above pairs is/are correctly matched?

Let's evaluate each pair based on known agricultural production: Kinnaur : Areca nut: This pair is incorrect. Kinnaur is a district in Himachal Pradesh, known for its temperate fruits, particularly apples and grapes. Areca nut (or betel nut) is a tropical crop primarily grown in humid coastal and high-rainfall regions of South India (e.g., Karnataka, Kerala) and Northeast India. Mewat : Mango: This pair is incorrect. Mewat (now Nuh district) is a region in Haryana, characterized by semi-arid to arid conditions. While some horticulture may exist, it is not well-known for significant mango production. Major mango-producing states in India include Uttar Pradesh, Andhra Pradesh, Bihar, Karnataka, and Maharashtra, which have more suitable climates. Coromandel : Soya bean: This pair is incorrect. The Coromandel Coast is the southeastern coast of India. While the region is agriculturally productive, it is primarily known for crops like rice, groundnuts, and other coastal and tropical produce. Soya bean is predominantly cultivated in the central Indian states, such as Madhya Pradesh (known as the 'Soybean State') and Maharashtra, which have different agro-climatic conditions. Since none of the given pairs are correctly matched, the correct answer is 'None'.
