Answer:

Explanation:

It certainly isn't the last one. A theory is close to a guess. It fits all the known facts, but there is usually something missing. If someone figures out what is missing, usually by experiment, then the theory become a fact.

The rest of them (1 2 an 3) can all be true. 3 is the least viable. You have to be able to come up with a counter example to reject a theory.

I'm not sure about 2. New phenomena can still be part of current theories. Reluctantly, I wouldn't choose 2 because

1 is the best answer of a very poor lot. Do not be surprised if you use it, that it turns out to be wrong.

When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.
