The correct answer is: A. Valsad
Valsad is a district in the state of Gujarat, India. It is located in the south-western part of the state, on the border with Maharashtra. The district has a population of over 2.5 million people.
Valsad is a major agricultural district, and is known for its production of mangoes, bananas, and cashew nuts. The district is also home to a number of industries, including textiles, chemicals, and pharmaceuticals.
In 2017, the Government of Gujarat declared Valsad as the first integrated horticulture district in India. The aim of this initiative is to promote the development of horticulture in the district, and to improve the livelihoods of farmers.
The government has implemented a number of measures to promote horticulture in Valsad, including providing subsidies for the cultivation of fruits and vegetables, setting up cold storage facilities, and providing training to farmers.
The initiative has been successful in promoting the development of horticulture in Valsad. The area under cultivation of fruits and vegetables has increased, and the production of fruits and vegetables has also increased. The initiative has also helped to improve the livelihoods of farmers.
The other options are incorrect because they are not integrated horticulture districts.
