C Correct answer
Explanation

In RMAN, a channel represents a stream of data to a specific device type (like disk or tape) and corresponds to one server session. Channels are allocated to perform backup and recovery operations. Option A is incorrect - multiple target databases can share one recovery catalog. Option B is incorrect - RMAN scripts are stored in the recovery catalog, not the control file. Option D incorrectly describes the RMAN client; it's the channel that establishes server sessions.
