Answer 1

Answer: (D)

Lactobacillus promotes curdling of milk by creating an acidic environment. A vaccine is a biological preparation that provides active acquired immunity to a particular disease. It is made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. Human malaria is transmitted only by females of the genus Anopheles. Dengue is spread through the bite of the female mosquito (Aedes aegypti). Kharif crops are those crops which are grown in monsoon season from the month of June to September. They need more water than rabi crops for their growth and development. Broadcasting is the method of random scattering of seeds on the surface of the seedbed. It can be done manually or mechanically.

So, the correct answer is option D.
