C Correct answer
Explanation

In Oracle databases, redo log files can be multiplexed - meaning multiple copies of the same redo log group can be maintained simultaneously on different disks to protect against disk failure. The parameter file (spfile or pfile) is a single configuration file. Data files cannot be multiplexed - they are the actual storage for database data. The alert.log is a single text file that records database events and cannot be multiplexed.
