Is this mold?

So i live in these apartments I absolutely hate, and I happened to see this in the kitchen

I don’t know if it looks like mold or not. I just want to be 100% sure so that way I can break the lease. I just cannot have my children living in this condition.

And if this does happen to be mold, can I legally break the lease without getting fined by them?

UPDATE: I forgot to mention I have told them about the mold 3 times now but they still haven’t attempted to look at it or bother and I asked for a work order but they are refusing to give me a copy of my work orders
