When is the manual removal of oil by hand most likely to be used?

A.) When the spill is far out at sea
B.) When the oil has sunk to the bottom
C.) When heavy equipment cannot reach the spill
D.) When the oil has already started to break down

When the oil breaks down, there are high chances that it can get absorbed at the surface of beaches consisting of sand, gravel, or cobble which cannot be cleaned otherwise. In such scenarios adsorbents are placed manually to soak the oil spilled on beach. Mostly shorelines are cleaned using these manual processes, otherwise inner oil spills are cleaned by machines only.

Hence, option D is the correct answer.
