B Correct answer
Explanation

The permission string 'prwxrwxrwx' indicates a FIFO (first-in, first-out) special file, also known as a named pipe. The first character 'p' identifies the file type as a pipe. FIFOs are used for inter-process communication, where data written to the pipe is read in the same order. This is distinct from regular files (-), directories (d), or sockets (s).
