M: Are you looking forward to your trip to Canada, Susan？
W: I can"t wait to see Canada, Jason, but I"m scared stiff of the journey. My husband insists on flying, but I want to sail. Planes make me nervous.
M: There"s nothing to be frightened of. How many planes fly across the Atlantic every day？
W: I"ve no idea. Hundreds, I suppose.
M: And how often do you hear of a crash？ Once or twice a year？
W: Yes, but aero-planes fly so high and fast that once is enough.
M: There are more road accidents per day than air deaths per year. Air transport is really safe compared with road transport.
W: I still prefer to go by sea. Ships may not travel fast but as least you can relax. I"d love a trip on a luxury liner like the Queen Elizabeth II.
M: It"s fine if you"re a good sailor, but have you ever traveled far in a rough sea？
W: No. I"ve only been in a boat once. I sailed down the River Thames on a sightseeing tour, but in any case I"d rather be sea-sick than dead.

A. Taking a voyage.
B. Taking a train.
C. Taking a flight.请帮忙给出正确答案和分析，谢谢！
