So, are we looking in the mammal statement for one premise, one conclusion, and the overall argument?

For example,

Not every mammal is suitable to keep as a pet - argument

Tigers are very aggressive - conclusion

and can cause serious injuries - premise

Or if not this, what would it be and what should we continuously look for.

Can we submit one of our practices to get feedback on what to improve? Are we allowed to have Grammarly enabled when we take the actual LSAT writing?

I am still not understanding why the answer would not be B. How can someone explain this without the lawgic language?
