B Correct answer
Explanation

Normal haemoglobin range for healthy adults is 12-18 g/dL (grams per deciliter). Males typically range 13.5-17.5 g/dL, while females range 12-15.5 g/dL, making 12-18 an acceptable general range. Option A (10-16) is too low for adults, Option C (14-20) is too high, and Option D has a typo (decilier) plus incorrect range.
