C. 0.36

Step-by-step explanation:

There is already a 45% chance of having oil on the land.

The oil kit has an 80% accuracy rate.

Therefore the kit has an 80% chance, of that 45% chance, of detecting oil. (Assume the owners in the area are correct in their 45% assumption)

This can be expressed as 80%*40% or 0.8*0.45

= 0.36 or 36%
