The correct answer is Option (2) → Study of writing styles

'Palaeography' refers to the study of writing styles.

Inscriptions are writings engraved on hard surfaces such as stone, metal or pottery. They usually record the achievements, activities or ideas of those who commissioned them and include the exploits of kings, or donations made by women and men to religious institutions. Inscriptions are virtually permanent records, some of which carry dates. Others are dated on the basis of palaeography or styles of writing, with a fair amount of precision.
