B. all of those.
just to clarify,
HDMI is the port for monitor and sound.
VGA is for video/monitor port
and display port.... I don't know, but it's a type of monitor port.
It is both true that <span>Technician A says that the excessive length of a heater hose is intended to protect the heater core from undue stress. Technician B says that excessive wear adds to the length of a heater hose, and a replacement heater hose should be roughly three to four inches shorter than its predecessor. So the asnwer is letter B.</span>
