Answer
c=32.5 mL
Work Step by Step
Surface of the liquid in graduated cylinder is curved and it is called the meniscus. This is because water molecules are more attracted to glass than to each other (adhesive forces are stronger than cohesive forces). When we read the volume, we read it at the bottom of the meniscus.
The smallest division of this graduated cylinder is 1 mL. Therefore, our reading error will be 0.1 mL or 1/10 of the smallest division.
An appropriate reading of the volume is 32.5 mL
