The pair of minerals most likely to be found in felsic rock is quartz and feldspar.

Here's why:

* Felsic rocks are light-colored, rich in silica (SiO2), and typically have a high percentage of potassium (K), sodium (Na), and aluminum (Al).

* Quartz is a silicate mineral composed entirely of silicon and oxygen (SiO2). It is a common constituent of felsic rocks due to its high silica content.

* Feldspar is a group of silicate minerals that are the most abundant minerals in the Earth's crust. Felsic rocks are particularly rich in alkali feldspars (orthoclase and albite) due to their high potassium and sodium content.

Other minerals commonly found in felsic rocks include mica (biotite or muscovite) and small amounts of amphiboles.
