Which of these is a serious allergic reaction that is rapid in onset and may cause death?

my 14 year old niece ingested a teaspoon of peanut sauce, she went into convulsions was in a coma for 3 days and passed away. No one knew she had nut allergies.

I had an allergic reaction a few years ago after eating a KFC.Had hives,blocked throat etc and ended up in hospital,vomiting and with low blood pressure.Very scary and was kept in overnight.Had allergy tests and unsure what caused it.Have to carry epipen everywhere now.

I had an anaphylactic episode after eating tilapia (fish).
