The question is referring to the use of functional near-infrared spectroscopy (fNIRS) to measure changes in oxygenated hemoglobin in the infants' brains. The increase in oxygenated hemoglobin indicates increased neural activity in response to the familiar language, while the decrease in oxygenated hemoglobin indicates decreased neural activity in response to the unfamiliar language. Therefore, the best answer is D, which indicates an increase in oxygenated hemoglobin for the familiar language and a decrease for the unfamiliar language.
