A recursively enumerable language L can be recursive if:

A recursively enumerable language L can be recursive if: Correct Answer L’ is recursively enumerable and every possible sequence of moves of T, the TM which accept L, causes it to halt

Theorem- If L is a recursively enumerable language whose complement is recursively enumerable, then L is recursive.
