Final answer:
Geology is the physical science best suited for finding the best locations to drill for petroleum used in making candles.
Step-by-step explanation:
The physical science that is best for finding the best locations to drill for petroleum used to make candles is Geology.
Geologists study the composition, structure, and processes of the Earth's crust to identify areas with potential petroleum reserves. They use various techniques such as seismology, satellite imaging, and geological surveys to locate underground deposits of petroleum.
By analyzing rock layers, fault lines, and other geological features, geologists can identify areas where petroleum is likely to be found, helping to determine the best locations for drilling.
