A、 go there with his relatives
B、 go at 7:00—8:00a.m.
C、 go with some alcoholic drinks for your friend
D、 be not suffering illnesses that can be easily passed on

【正确答案】 D

【答案解析】可以从最后一栏——探病者——中看到“Visitors with any signs of a cold，flu or other infectious illnesses not allowed in the wards”，即有任何患有传染病迹象的探病者都是不允许进入病房的，因此确定D选项是正确答案。
