D. Rock type
Explanation:
The major factor that influences the strength of rocks is the rock type.
Different rock types are known to have their own relative strength.
Based on their strength, rocks are classified into hard and soft rocks.
Soft rock types are dominated by sedimentary rock. Sedimentary rocks are formed by accumulation and deposition of sediments. They are often layered.
Metamorphic and igneous rocks are usually classified as hard rocks. These rocks forms under very high temperature and pressure conditions.
In engineering applications, the soft rocks not desired for construction purposes although they have their own unique material functions.
Hard rocks are used for heavy duty and durable constructions like dams and bridges.

Sustainable use practices are practices that are used in the use of resources for example that seek to maintain the longevity and continuance of the potential use of that resource. In regards to trees and logging the sustainable use of wood or paper would seek to continue the longevity and vitality of the forests by not overusing these products. Sustainable use will use a resource at a rate that will allow for natural replenishment or incremental use of the resource to prevent harm to the environment and allow the resource to be used far into the future.
