Correct answer: (B) Oxygenated haemoglobin absorbs less 600 nm visible light than deoxygenated haemoglobin; (D) Oxygenated haemoglobin absorbs more 900 nm infrared than deoxygenated haemoglobin
Explanation
The absorption spectra differ: deoxygenated haemoglobin absorbs more strongly in the red visible region around the stated wavelength, whereas oxygenated haemoglobin absorbs more strongly near nine hundred nanometres. Comparing these bands enables optical oxygenation measurement. Thus B,D.
