Section 10 of the CISF Act deals with the duties of members of the force (protection of industrial undertakings, etc.). Section 11 deals with the power to arrest without warrant. Section 12 deals with the procedure after arrest (handing over to police, etc.). Section 13 deals with the power to search without warrant. All four statements are factually correct descriptions of the respective sections. However, since the options require selecting a subset, and option B combines Section 11 (power of arrest) and Section 12 (procedure after arrest), which are logically and procedurally linked, it is the most plausible intended correct answer among the choices provided, acknowledging potential ambiguity if all statements were intended to be selected.
