Which statement about Koplik spots is correct?

Explanation:
Koplik spots are an early diagnostic clue for measles. They appear as small blue-white or gray-white lesions on the buccal mucosa (inside the cheek) with a surrounding reddened area, during the prodromal phase before the rash. Their timing is important: they typically show up about 1–2 days before the measles rash and disappear as the rash appears. This makes them a strong indicator of measles in a patient with fever and respiratory symptoms. Therefore, the statement that Koplik spots appear before the rash in measles is correct. They do not appear after the rash, they are associated with measles, and they can occur in children (not only adults).
