CRRI develops new rice varieties and rice crop management techniques that help rice farmers improve the yield and quality of their rice in an environmentally sustainable way. The Institute works with its public and private sector partners in national agricultural research and extension systems in major rice-growing countries to do research, training, and knowledge transfer. It is situated in Cuttack, India. Thus, option B is correct.

Plant transformation mediated by the soil-plant pathogen Agrobacterium tumefaciens has become the most used method for plant transformation. A. tumefaciens naturally infects the wound sites in dicotyledonous plant causing the formation of the crown gall tumours. A. tumefaciensis is capable of transferring a particular DNA segment (T-DNA) of the tumour-inducing (Ti) plasmid into the nucleus of infected cells where it is subsequently integrated into the host genome and transcribed, causing the crown gall disease.

Flavr Savr was the first commercially available genetically modified food, specifically a tomato engineered for delayed ripening.

The Flavr Savr tomato was engineered by antisense technology to reduce the expression of polygalacturonase, an enzyme that breaks down pectin and causes softening.

Golden Rice is the well-known transgenic variety engineered to synthesize beta-carotene, a precursor to Vitamin A.

Transgenic tomatoes have been developed to express genes (like those for osmoprotectants) that allow them to grow in saline conditions.

Golden Rice is engineered to produce beta-carotene (the precursor to Vitamin A) and often contains ferritin to increase iron content.

Flavr Savr is a transgenic tomato created by genetic engineering to delay ripening.

This question is similar to 487034. Golden Rice is the famous transgenic rice variety associated with Vitamin A, though the term 'basmati' is often used loosely in textbooks to refer to improved rice varieties.
