To solve this problem, we need to find the unit rate, which is the amount of square kilometers covered per hour.
The oil spill covers 4 square kilometers in 1/4 of an hour, which means it covers 16 square kilometers in 1 hour (since 1/4 of an hour is the same as 1 hour divided by 1/4).
So, at this rate, the oil spill will cover 16 square kilometers in 1 hour.
Since we want to find out how many square kilometers it will cover in 2 hours, we multiply the unit rate by 2:
16 square kilometers * 2 = 32 square kilometers
Therefore, the correct response is:
32 square kilometers
