Plant with oddly shaped leafs

So I’m a newbie and thought I’d give growing a shot I know I’ll have a lot of trial and errors to go through but my question is, Someone gave me some seeds, so I have 5 growing and 1 of them looks to be differently shaped than the rest.. or any I have ever seen for that matter. Can you tell me why? Or what it’s called?
I’ll post a picture of it compared to one of the others.
thanks!

Uhh..
You sure that's cannabis??

The first one isn't cannabis. Looks sort of like a tomato seedling.

Oregano

Common weed, or a marigold

First one looks like a marigold seedling.

Hahaha.. who ever gave you the seeds put a marigold in there to fuck with you.

Grow it out? bugs fucking hate marigolds.
