Answer

Answer:

  1. B. sedimentary
  2. C. trace

Brief Explanations:

  1. Sedimentary rocks form from the accumulation of sediments, which can preserve fossils well. Igneous rocks form from molten material and metamorphic rocks from heat - pressure transformation, making them less likely to preserve fossils.
  2. Trace fossils are signs of past life activity such as footprints or burrows, while organic refers to carbon - based material and periodic is not relevant in this context.
