Answer:
it would be C, D, E
A is a mixture
B is a mixture
C is a pure substance because Oxygen gas by the chemical symbol O2, is strictly pure
D is pure substance because Gold is one of the basic elements found naturally in nature, and as such, in its pure form
E is a pure substance because Both ice and liquid water are the same substance. H2O Though ice water is a mixture of both solid and liquid it is a pure substance, based on the molecular structure of its components .
F is a mixture

Explanation:
The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.

Hello there,
Natural photosynthesis is more effective as it is utilizes energetically efficient primary events of light capture and charge separation.
But Actual photosynthesis is used to help natural photosynthesis
Hope this helps :))
