Using a for-in loop, how do you print only the names of students who scored above 80?

Afor name in scores.keys { if scores[name] > 80 { print(name) } }

Bfor (name, score) in scores { if score > 80 { print(name) } }

Cfor score in scores.values { if score > 80 { print(score) } }

Dfor name in scores { if scores[name] > 80 { print(name) } }

Step-by-Step Solution
