是的，此题只能选 most of which，它用以引导非限制性定语从句。其中的 which 指代vitamins。又如：
The buses, most of which were already full, were surrounded by an angry crowd. 公共汽车大多数都已经挤满了人，它们被愤怒的人群包围着。
The treasure, most of which has been recovered, has been sent to the British Museum. 这些宝藏已送往大英博物馆，其中有大多数是失而复得的。
注意此题不能选 most of them，但如果前面有连词and，说成 and most of them 则完全可以。比较：
She wrote a lot of novels, most of which were popular.（most of which引导非限制性定语从句）
=She wrote a lot of novels, and most of them were popular.（and连接并列句）
她写过许多本小说，大多数都受欢迎的。
He bought a lot of books, most of which are about history. （most of which引导非限制性定语从句）
= He bought a lot of books, and most of them are about history. （and连接并列句）
他买了很多书，其中大多数是关于历史的。
