Best answer
Correct answer is (a) True

The explanation: Conventional breeding is often constrained by the availability of a limited number of disease resistance genes that are present and identified in various crop varieties or wild relatives. Inducing mutations in plants through diverse means and then screening the plant materials for resistance sometimes leads to desirable genes being identified.
