求助，有关二签签证填表问题

我是二签，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?
请问如果d为yes那么c,e是否也为yes?
"If the answer to any of the above is "yes", give details"是否要填拒签原因？
谢谢！
