Answer 1

Answer: the correct answer is c. Stevens-Johnson syndrome

Explanation:

Stevens–Johnson syndrome (SJS) is a type of severe skin reaction. It typically involves the skin and the mucous membranes. Together with toxic epidermal necrolysis (TEN) and Stevens-Johnson/toxic epidermal necrolysis (SJS/TEN), it forms a spectrum of disease, with SJS being less severe. It seems to be the flu at the beginning. The Early symptoms of SJS include fever and flu-like symptoms.
