Step 1: Evaluate each option.
- Option (A) is correct because taphonomy involves studying fossilization pathways from the time of an organism's death until its eventual recovery as a fossil.
- Option (B) is incorrect because biostratinomy involves the study of processes from burial to recovery, not the full fossilization process.
- Option (C) is incorrect because biostratinomy is a part of taphonomy but does not describe biostratigraphy, which is concerned with the use of fossils to identify and correlate strata.
- Option (D) is partially correct but incomplete because taphonomy includes not only the burial of organisms but also the processes before and after burial, including fossilization.
Step 2: Conclusion.
Thus, (A) is the correct answer, as it accurately defines taphonomy.
