Boll-guard II cotton contains the genes:

Correct option is C

Bollgard II is a genetically modified (GM) variety of cotton developed to provide enhanced protection against bollworms and other Lepidopteran pests. It is an improved version of Bollgard I, and it incorporates two Bt genes for broader and more effective insect control.
�� Bt Genes in Bollgard II:
· Cry1Ac:
· Targets early instar larvae of American bollworm (Helicoverpa armigera) and other Lepidopteran pests.
· Already used in Bollgard I.
· Cry2Ab:
· Provides additional protection by targeting late instar larvae and bollworms resistant to Cry1Ac.
· Broader spectrum and delays the development of resistance.
Together, Cry1Ac + Cry2Ab provide dual-gene protection, making Bollgard II more effective and durable in field conditions.
�� Advantages of Bollgard II Cotton:
· Controls a wider range of bollworms and Lepidopteran pests.
· Reduces the need for chemical pesticides, promoting environmental and economic sustainability.
· Delays pest resistance development due to dual-gene action.
· Provides longer-lasting protection compared to single-gene Bt cotton (Bollgard I).
