Answer

Answer:

A. patterns in their width, their density, and their composition

Brief Explanations:

Tree - ring width can indicate growth rate related to water and temperature. Density reflects physiological responses to climate. Composition can have chemical clues about environmental conditions. Odor and location are not relevant for climate - related tree - ring studies.
