德國鐵路訂票疑問 - 德國

各位好

我上德國鐵路網站訂票

訂票行程:從慕尼黑到蘇黎士 IC BUS

但出現如網址圖片所示http://ppt.cc/JKGy

內容如下

1.Exchange/refund, EUR 15; Excluded from the 1st day of validity.

2.Exchange and refund EUR 15; not possible after first day of validity.
Exchange/refund EUR 15; Excluded from the 1st day of validity.


請問我應該要選擇哪一個訂票?

謝謝
