Which one of the following is correct?

Correct option is A

The correct answer is (a) Pyroxene is commonly found in meteorites.
Explanation: Pyroxenes are a group of silicate minerals commonly found in igneous and some metamorphic rocks. They are indeed significant in meteorites, particularly in stony meteorites (chondrites) and also in other celestial bodies. Pyroxenes contain minerals like augite and enstatite, which are abundant in meteoritic material. This makes option (a) the correct answer.
Information Booster:
● Pyroxenes are crucial for studying the formation of meteorites and planetary bodies. ● Amphiboles are silicate minerals too, but they are not as prevalent as 20% in Earth's crust; they make up only a small fraction. ● Quartz is an insoluble mineral in water due to its high stability and resistance to weathering. ● Sedimentary is derived from the Latin word "sedimentum," which means settling.
