a) flask; liters
b) beaker; liters
c) beaker; milliliters
d) graduated cylinder; milliliters

The "graduated cylinder" is measuring a "volume of water" in "milliliters".

Option: D

Explanation:

Measuring of "liquid" in "milliliters" we use "graduated cylinder". This represents the "volume of the water" or the "liquid". The "graduated cylinder" is labelled with the dimensions in the "milliliters". Measuring with "graduated cylinder" is some what difficult because of the "meniscus", this "meniscus" is the "curvature" of the surface of the water in the "graduated cylinder". The only problem is "meniscus" is attached to the edges of the cylinder but not in the middle of the cylinder. While looking at the cylinder the "meniscus" is not straight, hence the person should keep the "graduated cylinder" at his eye level.
