Final answer:
The volume of the stone is 17 mL, which is the difference between the initial and final water levels in the graduated cylinder (92 mL - 75 mL).
Step-by-step explanation:
The volume of the stone that was dropped into the graduated cylinder can be determined by the difference in water levels before and after the stone was submerged. As the initial water level was 75 mL and it raised to 92 mL after adding the stone, the volume of the stone is simply the difference between these two measurements.
The calculation is as follows: 92 mL (final water level) - 75 mL (initial water level) = 17 mL (volume of the stone).
Therefore, the correct answer to the question is a) 17 mLs.
