Answer is c) Verify the vga cable is connected

Explanation:

No video signal means that the projector is not receiving any data from the laptop. Verifying the cable connection should be the first test you should do.

If the cable is properly connected and the projector keeps showing that error then you can move on and perform additional tests, but the first requirement for establishing a connection is that the cable is properly connected.
