(D) An oil spill is vacuumed off the surface of the water.

Answer 1

The correct answer is option A, Bacteria are used to decompose an oil spill

Step-by-step explanation:

Bioremediation is a process which occurs either naturally or is mechanically introduced to consume/breakdown the environmental pollutants to reduce the concentration of hazardous waste at a contaminated site. It is usually done in a non-sterile environment in such a way that the microorganisms which are introduced in it get adapted to the local ecosystem.

Some common application of bioremediation technology involves on- or off-site treatment at surface or in situ treatment.
