according to the rock - fossil layers shown in the figure below, which statement is true? (sc.7.e.6.3)\nfossil c is younger than d, but older than b.\nfossil b is younger than a, but older than c.\nfossil a is the oldest.\nfossil d is the youngest.

Answer

Answer:

Fossil A is the oldest.

Explanation:

Step1: Recall geological principle

In undisturbed rock - layers, older fossils are in lower layers.

Step2: Analyze fossil positions

Fossil A is in the lowest layer among A, B, C, and D. So it is the oldest.
