I chose statements 3, 4 and 5 based on the older answered Chegg questions but they were wrong.

Answer 1

Answer:

3. Animals depend on plants for them

4. Cannot live without them

5. Plants and bacteria has got enzymes for their synthesis

6. We cannot synthesize them because we lack enzymes for their synthesis

The statement 5 is only partially correct. That's to prepare vitamins like vitamin C, humans lack enzyme. Vitamins like vitamin D can be made by sunlight exposure in humans.
