Answer

Brief Explanations:

Fossils formed by sediments in sedimentary rock include molds and casts. Molds are impressions left by organisms, and casts are formed when the mold is filled with sediment. A frozen animal is not formed by sediments in sedimentary - rock (it's related to cold environments), and a preserved insect is often in amber (not sediment - formed in the same sense as molds and casts). Petrified wood is formed by mineral replacement but not in the same sediment - casting/molding process as molds and casts. Molds and casts are typical sediment - formed fossils in sedimentary rock.

Answer:

A. a mold of a fish skeleton and a cast of a clamshell
