Answer

Brief Explanations:

Absolute dating of sedimentary layers often involves radiometric dating. This means measuring the decay of radioactive elements in the rock layer to determine its age. Intrusions and extrusions can be dated to infer sedimentary layer age too as they cut through or are deposited on sedimentary layers. Comparing relative ages is relative - dating method, not absolute. Identifying fossils in intrusions/extrusions is not a typical absolute - dating method for sedimentary layers.

Answer:

A. by dating the age of several radioactive elements in a sedimentary rock layer B. by dating the age of intrusions and extrusions near a sedimentary rock layer
