Final answer:
Almandine is a type of garnet, a silicate mineral commonly found in certain types of metamorphic rocks such as eclogite, which consists of garnet and pyroxene. Option d is correct.
Step-by-step explanation:
Almandine is an example of a d. garnet. Garnets are found in a wide range of colors and chemical compositions, which determine the specific variety of garnet.
Almandine is a particularly common type of garnet, known for its deep red color. It is often found in metamorphic rocks, such as eclogite, which is a metamorphic rock composed of garnet and pyroxene and is associated with high pressure and temperature conditions also known as a metamorphism facies.
