Understanding the m-gate, n-gate, & h-gates correctly, please!!!

I'm having conflicting information regarding which gates are open/opening vs. closed/closing during different membrane states: Which of the following voltage gated positions best represents the repolarization phase? A) m gate open; h gate closed, n gate open. B) m gate close; h gate closed, n gate open. C) m gate open; h gate open, n gate open. D) m gate closed; h gate open, n gate closed. Here's what information I have, but I really don't feel like this gives me a clear enough... Understanding the m-gate, n-gate, & h-gates correctly, please!!!
