A plum variety has been genetically modified so that its fruit ripens more slowly after it is picked.
Which consequence of this modification could reduce food losses before the fruit is sold?
The picked plums keep photosynthesising, so they gain mass while in storage.
Each plum tree produces more fruit, so a larger mass is harvested from it.
More of the picked plums stay firm enough to sell after transport and storage.
The plums stay on the tree for longer, so they grow larger before picking.
