Karnataka is a leading producer of this floricultural crop:

Roses
Marigolds
Jasmine
Orchids

The correct answer is: A) Roses.

Karnataka is the leading producer of roses in India. The state produces around 100 million roses annually, which is about 60% of the country’s total production. Roses are grown in the state’s Mysore, Mandya, and Hassan districts. The main varieties of roses grown in Karnataka are the hybrid tea, floribunda, and grandiflora roses.

Roses are a popular floricultural crop because they are beautiful and fragrant. They are used in a variety of applications, including cut flowers, potted plants, and rose oil. The rose oil industry is a major contributor to the state’s economy.

Marigolds, jasmine, and orchids are also important floricultural crops in Karnataka. However, they are not as widely grown as roses. Marigolds are grown in the state’s Dharwad, Haveri, and Bellary districts. Jasmine is grown in the state’s Shimoga, Chikmagalur, and Udupi districts. Orchids are grown in the state’s Kodagu, Dakshina Kannada, and Uttara Kannada districts.

All of these floricultural crops are important to the state’s economy. They provide employment to a large number of people and generate a significant amount of revenue.
