The correct answer is option b.

Explanation:

The study of the procedures by which the organic traces and remains are included in the fossil record is known as taphonomy. It is the subdiscipline of archaeology and paleontology and is primarily concerned with the features and context of fossil remains. Taphonomist refers to an individual who studies taphonomy. Hence, the option that is the study of how bone assemblages come to be buried is studied by a taphonomist.
