An onion farmer finds that after a long drought some of his onion plants are still alive. Which best explains why these onion plants were able to survive

during the drought?

1. These onion plants may have deeper root systems that allowed them to access water stored deeper in the soil.

2. These onion plants may have developed a protective layer over their leaves to reduce water loss through evaporation.

3. These onion plants may have adapted to store water in their bulbs to survive periods of drought.

4. These onion plants may have symbiotic relationships with beneficial soil organisms that help them access water and nutrients more efficiently.

The most likely explanation for the survival of these onion plants during the drought is that they have deeper root systems that allowed them to access water stored deeper in the soil. This would have enabled the plants to continue to receive necessary water even when the surface soil had dried out.
