关于合同成立的描述正确的是()。

A．采用合同形式订立合同的，自当事人一方签字或者盖章时合同成立

B．当事人采用信件、数据电文等形式订立合同的，收到信件或数据电文时合同成立

C．采用数据电文形式订立合同的，发件人的主营业地为合同成立的地点

D．当事人采用合同书形式订立合同的，双方当事人签字或者盖章的地点为合同成立的地点

答案

参考答案：D

解析：当事人采用合同书形式订立合同的，自双方当事人签字或者盖章时合同成立。当事人采用信件、数据电文等形式订立合同的，可以在合同成立之前要求签订确认书。签订确认书时合同成立。承诺生效的地点为合同成立的地点。采用数据电文形式订立合同的，收件人，而不是发件人的主营业地为合同成立的地点。所以，选项D符合题意。
