The correct answer is Floriculture.
Floriculture is the cultivation of flowers for commercial purposes. It is a branch of horticulture that deals with the production of cut flowers, potted plants, and other ornamental plants. Floriculture is a major industry in many countries, and it is estimated that the global floriculture market is worth over \$100 billion.
Aquaculture is the farming of aquatic organisms, including fish, shellfish, and algae. It is a rapidly growing industry, and it is estimated that the global aquaculture market is worth over \$150 billion. Aquaculture is used to produce food, feed, fertilizer, and other products.
Apiculture is the maintenance of bees, commonly in man-made hives, by humans. Most such bees are honey bees in the genus Apis, but other honey-producing bees such as Melipona stingless bees are also kept. A beekeeper (or apiarist) keeps bees in order to collect their honey and other products that the hive produces (including beeswax, propolis, pollen, and royal jelly), to pollinate crops, or to produce bees for sale to other beekeepers.
Sericulture is the cultivation of silkworms for the production of silk. It is an ancient industry, and it is estimated that silk has been produced for over 5,000 years. Sericulture is practiced in many countries, but China is the world’s largest producer of silk.
