Consider the following techniques/phenomena:

Budding and grafting in fruit plants
Cytoplasmic male sterility
Gene silencing

Which of the above is/are used to create transgenic crops?

Select an option to attempt

Explanation

A transgenic crop is a genetically modified organism (GMO).

Transgenic indicates that a transfer of genes has occurred using recombinant DNA technology. Generally, a transgenic crop contains one or more genes that have been inserted artificially either from an unrelated plant or from different species altogether.

Budding and grafting in fruit plants does not include genetic editing or modification. Thus, option 1 is eliminated.

Gene silencing technique uses engineered genetic material to specifically suppress the expression of certain genes in a plant. This allows scientists to modify the plant's characteristics at the genetic level, which is the hallmark of transgenic crops.

Thus, option 3 must be part of the answer, accordingly right answer is option 'B'.
