Final answer:
Among the options given, muscovite, hornblende, and plagioclase are the silicate minerals, which are essential components in various rock types and make up the majority of Earth's crust.
Step-by-step explanation:
The silicate minerals are those that include silicon and oxygen in their chemical composition, typically with metal ions. In the options provided, musovite, hornblende, and plagioclase are indeed silicate minerals. These minerals are part of various rock types including granite, arkose sandstone, and gneiss, which are described as containing K-feldspar, quartz, plagioclase feldspar, and biotite. All these minerals fall under the category of silicates as they share the fundamental building block of SiO44- tetrahedral structure. The Earth's crust is primarily made up of silicates, and this category includes a wide variety of minerals that are vital to understanding the composition and formation processes of rocks.
