Say, the target has 10 seconds of Poison left on him.

I hit him with a different move, which is supposed to poison a target for 5 seconds. Does it:

a) Change the duration to 5 because the newest duration takes priority
b) Stays 10 seconds because the original duration takes priority
c) Stays 10 seconds because the higher duration takes priority
d) Becomes 15 seconds because they stack (most likely not)

I made the same post on GFAQs, but couldn't get a straight answer, so I thought I'd try here.
