Explanation:

They are the Parent rock: This statement is correct. Igneous rocks are considered parent rocks because they are the primary rocks formed directly from the cooling and solidification of molten magma or lava.

Acidic igneous rocks are more viscous than basic igneous rocks: This statement is correct. Acidic (or felsic) igneous rocks, which are rich in silica, are more viscous than basic (or mafic) igneous rocks, which have lower silica content. Viscosity is influenced by silica content, with higher silica content leading to higher viscosity.

Deep-seated intrusive igneous rocks are called as Hypabyssal rocks: This statement is incorrect. Hypabyssal rocks are actually intermediate rocks formed from the cooling of magma at a shallow depth, not deep-seated intrusive rocks. Deep-seated intrusive rocks are typically referred to as plutonic or abyssal rocks.
