Which one of the following is not a suit of civil nature under C.P.C.?

A purely social claim about attending functions, without an associated enforceable civil right, is the non-civil claim intended here. Salary arrears, burial rights and restitution of conjugal rights concern recognised civil entitlements. Section 9 uses a broad civil-nature test; if exclusion from a function infringes a property, office or other legally protected right, that distinct claim can be civil despite its social setting.
