Answer:
Buret that had markings every 0.1 mL
Explanation:
Consider the measurement of the water which is 15.05 mL. Then consider the measurement marks of each of the instruments or apparatus used.
The clue there is 0.05 mL. Which instrument would be able to measure 0.05 precisely?
The best instrument used in this scenario that would be able to measure closest to 0.05 is the Buret, which has markings 0.1mL because the markings are the closest to 0.05mL, which would be half-way to the next mark.
In an experiment you need to consider precision, and all other apparatus given cannot give a precise measurement.
