Vref is 1.3 x VSo and normally is the speed to be achieved by the very latest of 50ft, the idea being that you bleed off the 0.3 by touchdown
Its fixed for a given configuration and for that configuration only changes with landing weight - not wx
The other gotcha is talk of increasing Vapp - which some people consider to be an approach speed - but its not its actually there to ensure you make a gradient in the go around scenario
So to get back to the Q. its D as all you would do is be stable down the approach at Vref + 10 + (X) as opposed to Vref +10.....where X can be any number of things - 1/2 the max gust capped at 20, 10knts, 20knts all depends on your ops manual and how brave you are feeling and how strong the wind is blowing!!!
