Identify the proper device for the third partition, on the second hard disk, on the first IDE controller on a PC system.

A.
/dev/hdb3

B.
/dev/hd1b3

C.
/dev/hdc1b3

D.
/dev/hdc1d2p3

Explanation/Reference:
For IDE drives:
primary master /dev/hda
primary slave /dev/hdb
secondary master /dev/hdc
secondary slave /dev/hdd
So the 3rd partition  on the second harddrive is /dev/hdb3 (or /dev/sdb3 for SCSI drives)
