请教二签的同伴

请教，有关二签签证填表问题
表中第12项填yes or no,以下为其中三条：
c) Been refused admission to, or ordered to leave Canada?
d) Applied for any Canadian Immigration visas
（e.g. Permanent Resident, Student, Worker, Temporary Resident (visitor), Temporary Resident Permit)?
e) Been refused a visa to travel to Canada?
应如何填写？
"If the answer to any of the above is "yes", give details"是否要填拒签原因？
谢谢！
