B and D are solutions
A is a suspension
C is either a suspension or a colloid (depending on the size of the algae and their ability to "clump" together)

do you mean true or natural? It depends on your definition of true.
Both coffee and algae are natural but if the coffee is sprayed too much, it could be deadly. Why is the algae there?
Rubbing alcolhol must have some mixture of elements.
Salad dressing has spices and oil and vinegar, etc.

I am assuming italian salad dressing because it is edible. The vinegar in it is a solution. But I don't really know.

Rubbing alchohol (alchohol and water). a. and c. will separate. Black coffee has a light oily film on the top that you can see in good light...it never really dissolves.

B is definatly a solution.
D might be a solution but I am not completly sure.
A and D are not solutions
All solutions have uniform composition.

DO YOUR OWN HOMEWORK - You can google the definition of 'solution' and figure it out for yourself.
