- C
The USB-C port on the laptop needs an adapter to connect to the monitor.
- D

Show answer and explanation
Correct answer: A
Explanation
The monitor does not support VGA connectivity, so using a VGA cable for the connection is the root issue. To resolve this, the user should use a compatible cable, such as HDMI or a USB-C to HDMI adapter, to connect the laptop to the monitor.
- A. Correct.
The VGA cable is incompatible because the monitor does not have a VGA port. The user must use a cable that matches the supported ports on both the laptop (HDMI or USB-C) and the monitor (HDMI, DisplayPort, or DVI).
- B. Incorrect.
The HDMI port being disabled is unlikely since the user is not attempting to use an HDMI cable for the connection.
- C. Incorrect.
A USB-C adapter would only be relevant if the user intended to use the USB-C port, but they are using a VGA cable instead.
- D. Incorrect.
It is unlikely that the laptop lacks support for external displays, as it has multiple video output ports such as HDMI, USB-C, and VGA.
