Explanation

IMPORTANT NOTE: The marked answer (B - vacuum) conflicts with CompTIA A+ best practices. The industry-standard correct answer is C (compressed air). Vacuums generate electrostatic discharge (ESD) that can permanently damage sensitive components like RAM, GPUs, and motherboards. Compressed air safely dislodges and expels dust without physical contact or static risk. A damp cloth introduces moisture danger, and a brush can also produce static. If your answer key marks B, it may assume a specialized ESD-safe vacuum, but on CompTIA A+ exams, compressed air is the expected correct answer.
