The arrow shows the wind direction relative to the aircraft. In this case it's coming from the front and just off to the right. The aircraft is tracking 073ºM, you can see that at the top of the compass arc, and the wind arrow is coming from about 20º right of that. If you want to be mega accurate, parallel the wind arrow through the pointy nose of the aircraft symbol and extend it up to the compass arc at the top of the ND. The only answer that's even close has the wind coming from 105º. Wind speed is not an issue in the answers, they are all 20kt, and canot be determined from the ND as shown. What has been taken out of the diagram is the wind speed or w/v which would be shown next to the wind arrow as "20" or "105/20".
