OPTION A - INCORRECT
This is so untrue in in quite an absolute manner depicting what the post represents when it comes to weather forecasting. Either of the weather conditions or the mountain is yet unsafe to climb. Most likely the mountaineers want to also see what good weather looks like at the mountain top and never went precisely because of the forecast weather condition.

OPTION B - CORRECT
Certainly, yes and very much true that the good weather condition gave them a clearer view of the mountain. Hence, it encourages them to climb more with the fact that they probably can see the summit more clearer. However, if the weather was poor, they wouldn't have had the urge to go farther as 26,000ft. That's obviously unattainable if the weather condition were to be poor.

OPTION C - INCORRECT
This is entirely false. There is no way the good temperature can make the "death-zone" warmth than the recent years because there's nothing special about 2006 that makes it better than the recent years. Mountaineers have been eager to get to the summit of the mountain. Then the good temperature boosted the eagerness but certainly not the reason they decided to proceed higher.

OPTION D - INCORRECT
This option is inaccurate in all totality. Modern equipment has more or less zero effectiveness when it comes to bad weather. "Weather", especially that of bad conditions can undeniably hinder the working conditions of the modern day equipment hereby causing even higher cases of fatality.

OPTION E - INCORRECT
This is so wrong. Good weather or not, Mt. Everest has always been seen more like a suicidal mission regardless the condition. No accomplished climber dares MT. Everest because it is beyond a challenge especially when it comes to getting a major feet as that of 26000ft, not to talk of the summit. Well informed climbers avoid going closer to the tallest mountain regardless of the weather conditions
