Which of the following statements is true?
(a) flavr savr tomatoes are still commercially successful.
(b) a large percentage of us crops are currently genetically engineered
(c) glyphosate kills all plant life, even genetically altered plants.
(d) none of these is true

The correct answer is option A.

Explanation:

A genetically modified tomato known as Flavr Savr was the initial commercially developed genetically engineered food that was given license for human use. In the Flavr Savr tomatoes, the gene, which is accountable for ripening  is amended with the help of genetic engineering procedure, so that the shelf life of tomato get enhanced, or it can be said that the procedure of ripening in tomatoes get slow down due to genetic changes, that is, by minimizing the expression of already prevailing gene.
