Correct option is C
Argillaceous rocks are sedimentary rocks that are primarily composed of clay minerals or fine-grained materials. These rocks are rich in alumina and silica and are often formed through the weathering of silicate rocks under specific environmental conditions.
Options Analysis:
Syenite:
It is an igneous rock composed mainly of feldspar and ferromagnesian minerals.
Not an argillaceous rock.
Dolomite:
It is a sedimentary rock composed mainly of the mineral dolomite (calcium magnesium carbonate).
Not an argillaceous rock.
Laterite:
It is a sedimentary rock rich in iron and aluminum, often formed in tropical and subtropical regions through intense weathering of rocks.
It contains significant clay content, making it an argillaceous rock.
