No, we call something mafic if it has a relative low silica content. As quartz is 100% silica, it's not mafic, but felsic.
mafic rocks can be made up of orthoclase feldspar and quartz
Quartz, feldspar, mica, and pyroxene are common members of the silicate mineral family.
Plagioclase feldspar is a common mineral in igneous rocks, while quartz is a mineral often found in a variety of rocks. Olivine is a green mineral commonly found in mafic igneous rocks. When all three minerals are present in a rock, it typically indicates a mafic igneous rock such as basalt or gabbro.
First of all there is no such thing as a mafic or a felsic "mineral". There can be mafic and felsic rocks.Mafic rocks have a high magnesium and iron content.Felsic rocks enriched with lighter elements such as oxygen and silicon.
Felsic rocks are primarily composed of minerals like quartz, feldspar, and muscovite, while mafic rocks contain minerals such as olivine, pyroxene, and plagioclase. Felsic rocks have lighter-colored minerals and lower density compared to mafic rocks, which have darker-colored minerals and higher density.
Quartz monzonite ranges from intermediate to felsic.
silicate oxygen and quartz
A plutonic rock consisting of oligioclase, microcline and quartz with subordinate muscovite and little or no mafic minerals. An alkali granite with no mafic minerals
No, diorite is a simply an igneous rock with lots of mafic minerals and quartz.
The best anwser would be A, that they contain quartz.

When all three minerals are present in a rock, it typically indicates a mafic igneous rock such as basalt or gabbro.
Felsic rocks are typically composed of minerals such as quartz, potassium feldspar, plagioclase feldspar, and muscovite mica. These minerals are light in color and have lower densities compared to mafic rocks.
Mafic rocks have higher concentrations of dense minerals like iron and magnesium compared to felsic rocks, which are rich in lighter minerals like quartz and feldspar. This difference in mineral composition contributes to the higher density of mafic rocks.

Felsic rocks are light-colored, rich in silica and aluminum, and have high viscosity when molten. They contain minerals such as quartz and potassium feldspar. Mafic rocks are dark-colored, rich in magnesium and iron, have low viscosity when molten, and contain minerals like olivine and pyroxene.
