Kalyan Sona is
A) Hybrid variety of rice and maize
B) Hybrid variety of wheat and rye
C) High yielding variety of wheat
D) High yielding variety of rye

Hint: As technology is hastening up the world, it has been implemented in the field of agriculture too. Plants are genetically engineered to provide high yield and to be disease resistant. Kalyan Sona is such an example of genetically modified plant to give more yield than the normal yield.

Complete explanation
Option A Hybrid variety of rice and maize: The term hybrid means that the offspring is produced by the cross between two different species of plants. Kalyan Sona is not a hybrid variety of rice and wheat.
Option A is not correct.
Option B Hybrid variety of wheat and rye: Hybrid plants are resultants of a cross between two different species. Kalyan Sona is not a hybrid variety of wheat and rye.
Option B is not correct.
Option C High yielding variety of wheat: Genetically modified plants are produced in the aim to provide high yield. Many plants like rice, wheat, rye, maize etc. are genetically modified. Kalyan Sona is a high yielding variety of wheat.
So, option C is correct.
Option D High yielding variety of rye: Rye is a plant related to the families of wheat and barley. These plants are genetically modified to provide high yield. But, Kalyan Sona is not a high yielding variety of rye.
Option D is not correct.

So, Option C is the correct answer.

Note:
Many plants are genetically modified to provide high yield. Kalyan Sona is a genetically modified wheat also known as dwarf wheat to provide high yield to farmers. This dwarf wheat is rich in starch and gluten and proves to be nutritious. These plants are also resistant to different drugs.
