There seems to be a formatting problem with the question text. I have rewritten the question as follows.
Question 21 (the correct answer is now (d).
Your aircraft has a maximum crosswind component of 20kt. If you conducted flight of 70nm by day, which of the following items in the destination aerodrome TAF would always impose an alternate requirement?
(a) a forecast wind on the only runway in excess of 20kt
(b) 4/8 cloud with a base of 1200ft AGL
(c) 6/8 cloud with a base of 1500ft AGL
(d) a crosswind on the only runway in excess of 20kt
