For selecting my suggestion as the winner, I would like to thank you and your company. I express my deepest gratitude and am very honored to receive this award. My purpose in writing this email is to express my appreciation and to ask a few questions. Please let me know the date and time of my arrival at your factory in Switzerland and when I shall return. Furthermore, I would like to inquire about the travel arrangements, and what kind of vehicle we will be traveling with. Last but not least, I would like to ensure that my friend will not have to pay for travel or accommodations. Thank you again for this wonderful opportunity. It is a pleasure to meet you and to see your factory.
The answer is B. because it shows how it looks. C. is confusing because you think of stormy as an adjective, but it's actually just a verb because it IS storming.
