Breeding of crops with high levels of minerals, vitamins and proteins is called

The correct option is D Biofortification

• Biofortification is the technique of breeding crops to increase their nutritional value. This can be done either through conventional selective breeding or through genetic engineering. It differs from ordinary fortification because it focuses on making plant foods more nutritious as the plants are growing, rather than having nutrients added to the foods when they are being processed.
• Micropropagation is the practise of rapidly multiplying stock plant material to produce a large number of progeny plants, using modern plant tissue culture methods.
• The process by which protoplasts of two different plant species fuse to form hybrids is known as somatic hybridisation.
• Biomagnification is the incremental increase in a contaminant's concentration at each level of the food chain

So, the correct answer is 'Biofortification'.
