Final answer:
The claim in the question is not entirely accurate because research by Thomas Fritz and his team demonstrated that music can evoke universal emotional responses across cultures, showing that the impact of music can be both personal and universal.
Step-by-step explanation:
The claim that it is not possible to collect data on the physiological impact of music on humans because music is subjective and varies individually is not entirely accurate. The correct answer to the multiple-choice question is B) Personal. Research has shown that despite the personal and subjective nature of musical experience, there are aspects of music that can have universal emotional effects across different cultures. This is evidenced by a study led by Thomas Fritz of the Max Planck Institute, which found that the Mafa tribe in Cameroon could recognize emotions in Western music despite having no previous exposure to it. Hence, while music can be personal in how it affects individuals, there's also a universal component to its impact that allows it to be studied scientifically.
