Explanation:

1. The phrase "who won a prestigious art award last year" is non-essential (it provides extra, non-required information about Adriana). Non-essential clauses can be set off with commas, em dashes, or parentheses.
2. Option 1 is incorrect: it uses no punctuation for the non-essential clause, creating a run-on error.
3. Option 2 is correct: commas properly set off the non-essential clause.
4. Option 3 is incorrect: the em dash is placed incorrectly, splitting the main verb phrase "is studying" improperly.
5. Option 4 is correct: em dashes properly set off the non-essential clause.
6. Option 5 is correct: parentheses properly set off the non-essential clause.

B. Adriana, who won a prestigious art award last year, is studying painting in school.
D. Adriana—who won a prestigious art award last year—is studying painting in school.
