The correct answer is A. The correct measurement for the volume of the liquid shown is 8.5 mL. If the volume of water to be read in a graduated cylinder, it is important to read it in the lower meniscus. This will be the correct reading. Due to surface tension, water attach to the walls of the glass forming a concave at the top surface.
It hits the tick mark at 8.5. You can cross out 85 and 87 right away. and then you just need to know that the liquid was probably moving but when it settles it will be 8.5
