Answer:
I believe the answer is A.
Explanation:
This section states that protozoa live in all bodies of water therefore B can not be an answer because it says protozoa dose not live in any body of water.
I hope this answers your question.
The answer is 0.18
Because the equation for finding the molarity of a solution is:
Moles divided by Liter of solution,
so, you dissolve 0.32 mol of KCL in 1759 ml of Water 1759 ml is 1.759 liters when you plug the numbers in you get 0.18

The downward or upward curve at the surface of liquid in a container is said to be the meniscus of the liquid, which occurs due to the surface tension. This curve can be concave or convex depending on how the molecules of liquid interact with surface of the container. The reading of the meniscus should always be done at the eye-level.
When the particles of the liquid are more attracted to the container than to each other then a concave meniscus occurs whereas when the particles of the liquid are more attracted to each other than to the container then a convex meniscus occurs.
The bottom of the curve will be read for a concave meniscus and for convex meniscus, the top of the curve gives the correct reading of the volume of liquid.
