Parul has the most precise measurements. 

Answer:

Parul

Step-by-step explanation:

The more decimal places a measurement is carried out to, the more precise the measurement is.

Julian's measurements are to the nearest tenth of a second.

Mia's measurements are to the nearest second, as are Sonu's.

Parul's measurements are to the nearest hundredth of a second, so this is more precise.
