Explanation:

Civil courts generally have jurisdiction over all suits of a civil nature unless expressly or impliedly barred. However, specialized tribunals and authorities are established by specific statutes to handle particular matters, thereby excluding the jurisdiction of civil courts. Income tax matters are handled by Income Tax Authorities/Tribunals, industrial disputes by Labour Courts/Industrial Tribunals, and service matters by Administrative Tribunals. Therefore, a civil court does not have jurisdiction to try any of the suits mentioned in options A, B, or C.
