甲与某保险公司订立了一份健康保险合同，并交付了全部保费。之后保险公司一直未将保险单交付甲。甲于保险合同签订一星期后因病住院治疗。则依据《保险法》的有关规定，下列说法正确的是（）。
A.保险合同因保险公司未签发保险单而无效
B.保险合同因保险公司未签发保险单而自动解除
C.保险合同因保险公司未签发保险单而可撤销
D.虽然保险公司未签发保险单，但保险合同仍然有效，保险公司应当按合同约定承担给付责任
参考答案：D
解析：《保险法》第十三条第三款规定，依法成立的保险合同，自成立时生效。甲与保险公司订立了保险合同且交付了全部保费，保险公司未能及时交付保险单不影响保险合同的效力。保险合同已经生效，保险公司应当按合同约定承担责任。
