B. tiny algae and plankton decomposed under conditions of heat, pressure, and low oxygen.

Explanation:

Oil is most likely to form where tiny algae and plankton decomposed under conditions of heat, pressure and low oxygen.

  Coal will form when plant materials like twigs, leaves and tree trunks decomposed under conditions of heat, pressure and low oxygen.

  • To form oil, algae and plankton will be gathered with sediments in a basin.
  • Rapid burial causes the algae and plankton to be cut off from aerobic environment that would lead to the decay of these organisms.
  • They are buried alive and as the basin subsides, temperature and pressure acts to produce kerogen.
  • Further cracking produces oil and gas.
