Expert verified

a) Animal grazing to control weed growth b) Fish farming of Gambusia to control malaria c) Bombyx mori used for apiculture d) Bee wax usage in various products Answer: (c) Bombyx mori is the widely used honey bee variety used for apiculture.

Step by step solution

It is commonly known that animal grazing can be used as a method to control weed growth, as the animals consume the weeds while grazing. As a result, the weeds are thinned or eliminated. Therefore, statement (a) is correct. #Step 2: Fish Farming of Gambusia to Control Malaria

Gambusia (mosquito fish) is a type of fish that is known to feed on mosquito larvae, helping control the population of mosquitoes. Since mosquitoes are carriers of malaria, the use of Gambusia for fish farming can help in controlling the spread of the disease. So, statement (b) is correct. #Step 3: Honey Bee Variety for Apiculture

Bombyx mori is known as the silkworm moth. It is not used for apiculture (the process of beekeeping). For apiculture, the most widely used honey bee variety is Apis mellifera. This makes statement (c) incorrect. #Step 4: Bee Wax Usage

Bee wax, produced by honey bees, is used in various products like cosmetics, polishes, and other applications due to its texture and properties. This makes statement (d) correct. The correct answer is: (c) Bombyx mori is the widely used honey bee variety used for apiculture.
