Concept:To compare units, convert everything to the same unit using standard conversion factors: 1 litre = 1000 mL, 1 m = 100 cm, 1 kg = 1000 g.
Explanation:Check each option one by one.
Option A: 2 litres = 2 × 1000 = 2000 mL. 2000 mL is much more than 205 mL. So false.
Option B: 1.69 m = 1.69 × 100 = 169 cm, not 1690 cm. So false.
Option C: 6.25 litres = 6.25 × 1000 = 6250 mL. 6 litres 25 mL = 6 × 1000 + 25 = 6025 mL. Since 6250 > 6025, this statement is true.
Option D: 9 kg 75 g = 9 × 1000 + 75 = 9075 g, not 975 g. So false.
Answer:Option C: 6.25 litres is more than 6 litres 25 mL.
