Correct Answer: 1-c, 2-d, 3-e, 4-b, 5-a

Principle	Method / Instrument / Condition
Crude Protein (CP)	Kjeldahl method — N% × 6.25 = CP%
Ether Extract (EE)	Soxhlet apparatus — petroleum ether solvent extraction
Total Ash	Muffle furnace — 600°C for 2 hours
Moisture	Hot air oven — 100°C for 1 hour
NFE	Calculated by difference: 100 − (CP + EE + CF + Ash)
