Determine the correctness of [a] Genetically engineered rice producing beta-carotene in its grain is called Golden rice; and [r] Provitamin A biosynthesis in rice endosperm gives a characteristic yellow/orange colour.
Both [a] and [r] are false.
Both [a] and [r] are true but [r] is not the correct reason for [a].
Both [a] and [r] are true and [r] is the correct reason for [a].
Correct answer: (C) Both [a] and [r] are true and [r] is the correct reason for [a].
Explanation
Beta-carotene is a carotenoid pigment and provitamin A. Engineering its synthesis in rice endosperm produces the characteristic golden coloration that underlies the name Golden rice. Consequently both statements are true and the reason explains the assertion. Under this option order the answer is C.
