Bollgard I and Bollgard II technologies are mentioned in the context of

A.clonal propagation of crop plants
B.developing genetically modified crop plants
D.production of biofertilizers
C.production of plant growth substances

Correct Answer: Option B

Bollgard I Bt cotton (single-gene technology) was the first biotech crop technology approved for commercialization in India in 2002.

Bollgard II (double-gene technology) followed in mid-2006, approved by the Genetic Engineering Approval Committee (GEAC).

Bollgard cotton offers built-in protection against the American Bollworm (Heliothis Armigera).

It contains an insecticidal protein from Bacillus thuringiensis (Bt).

Bollgard II contains Cry1Ac and Cry 2Ab, providing protection against bollworms and Spodoptera caterpillar, improving boll retention and yield, reducing pesticide costs, and protecting against insect resistance.

Both Bollgard I and Bollgard II are planted globally as an environmentally friendly bollworm control method.

Therefore, Bollgard I and Bollgard II technologies relate to developing genetically modified crop plants.

Hence, option (b) is correct.
