A doubly-linked list is a variation of the linked list in which each node has two pointers, one pointing to the next node in the sequence, and one pointing to the previous node in the sequence. This allows traversal of the list in both directions. 
A circular linked list is a variation of the linked list in which the last node in the list points back to the first node, creating a loop. This can be useful in certain applications, such as implementing a circular buffer. 
Therefore, the best choices for variations of linked list are A) doubly-linked list and B) circular linked list.
