Which pair correctly matches a pathogen with a toxin?

Tapeworm (toxin) and pesticide residue (pathogen contaminating fish harvested from polluted water systems where long-term low-level exposures are the primary concern).

Mercury (pathogen) and norovirus (toxin) where both are examples of organisms that cause rapid onset vomiting and diarrhea in most exposures.

Lead (pathogen) and salmonella (toxin produced in spoiled dairy products over long storage periods).

Norovirus (pathogen) and solanine (toxin produced in green potatoes).
