    I would say c, 5A. The 2A and 3A fuses would blow when its operating normally. If a fault develops and higher current is drawn, you should pick the smallest one that exceeds the operating current. If a fault/short develops, the 5A and 10A will blow but the 5A will blow first better protecting the device. So I would choose c, 5A.
