Siliceous rocks are sedimentary rocks that have silica (SiO2) as the principal constituent. The most common siliceous rock is chert other types include diatomite. They commonly form from silica-secreting organisms such as radiolarians, diatoms, or some types of sponges.

Geology - rocks, and minerals. Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock.

Quartzite (from German: Quarzit) is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.

It is silicious rock in its chemical composition but under the process of metamorphizm. So metamorphic is given in terms of method. And the other 3 option are given in accordance with chemical conpositio. So answer will be silicious rock.

You can say that Quartzite rock is metamorphic but ortho quartz is a pure form of quartz and its contain 99% amount of sio2 so its more convenient to say that its a silicious rock if.
We have to choose one answer to out of 4.

Chemically it is silicious and geologically it is metamorphic but both options are not available and generally, we believe that simply rock means geological classification so option A should be the answer.

Geological classification of quartzite is a metamorphic rock because it formed metamorphic action on sandstone.
Chemical classification is silicious rock. It is a non-stratified rock.
