Correct answer: C — Arrange post-exposure MMR if eligible and notify public health

MMR can be used as post-exposure prophylaxis in eligible contacts within a short window, and measles exposure requires public health involvement. Antibiotics and aciclovir do not prevent measles. Age, timing, pregnancy and immunocompromise determine whether MMR or immunoglobulin is used.
