Section 298B, of P.P.C. deals with offence of misuse of epithets, description and titles etc by

Section 298B of the Pakistan Penal Code (PPC) specifically addresses the misuse of religious epithets, descriptions, and titles. This section was enacted to prevent certain groups from using terms and practices that are considered exclusive to mainstream Islam.

• Option A: Quadiani group and Lahori group is the correct answer. These groups, also known as Ahmadiyya, are legally prohibited under this section from referring to themselves as Muslims or using Islamic symbols and titles, as their beliefs are considered distinct from mainstream Islam in Pakistan.
• Option B: Shia and Sunnies are mainstream Islamic sects, and Section 298B does not target them for misuse of epithets.
• Option C: Ahl-i-Kitab's refers to 'People of the Book' (Jews, Christians), and this section is not directed at them.

Therefore, the law specifically targets the Quadiani and Lahori groups to maintain the distinct identity of Islam as defined by the state.
