Answer:
A. The rice genes didn't make the right type of vitamin A.
Explanation:
Regular white rice does not have the gene to produce beta carotene. The human body converts the beta carotene into vitamin A.
To increase the nutritional value of rice, the gene for beta carotene from daffodil flowers was inserted into the cells of endosperm of rice.
This allowed these cells of the genetically engineered rice varieties to produce beta carotene. Production of beta carotene imparted golden color to the rice grain and hence, the name.

Answer</h2>
It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis.
The process is called OXIDATIVE PHOSPHORYLATION.
Oxidative phosphorylation is the process by which a free phosphate ion is added to ADP in order to produce ATP. This process take place in the mitochondrion and is a major source of energy for anaerobic organisms. The free phosphate ion is usually transferred from NADH or FADH2.<span />
