Correct option is B
A pin vice is a small hand tool consisting of a handle and a collet chuck at one end. It is used to hold small tools such as drill bits, wires, or pins for precision work. The collet chuck allows secure gripping of very small diameter objects.
Other types of vices serve different purposes: a hand vice is used for holding small workpieces, a pipe vice holds pipes, and a toolmaker’s vice is used for precision machining work. None of these have a collet chuck design like a pin vice.
