Plain English Meaning
The wrong answer choices on a multiple-choice question that are designed to look believable, usually based on the mistakes students often make.
Full Definition
In multiple-choice test writing, popular distractors are the incorrect answer choices that students most commonly select instead of the correct answer. They are typically built from frequent student errors, common misconceptions, or partially correct reasoning, and are used to make a test question genuinely discriminating between learners who understand the material and those who do not.

Derivation
Distractor comes from the Latin distrahere, meaning 'to pull apart' or 'draw away.' A distractor is something that pulls attention away from the correct answer. 'Popular' here means 'commonly chosen,' not 'well-liked' — these are the wrong answers students gravitate toward most often.
