Answer:
C. Professional service technicians use grounding straps to minimize the chances of electrostatic discharge (ESD) during normal computer maintenance work involving electronic devices. These antistatic devices can be placed around the wrists or ankle to ground the technician to the system being worked on. These straps release any static present on the technician's body and pass it harmlessly to ground potential. Surge protectors (Answer A) are used to protect from power surges, not ESD. Screwdrivers (Answer D) will not dissipate ESD. A terrycloth towel (Answer B) will most likely cause electrostatic discharge.
