The passage highlights how neurotechnology, particularly brain-computer interfaces (BCIs), offers promising new ways to treat neurological disorders and enhance cognitive abilities. However, it also points out key challenges:
Security of neural data: Because BCIs deal with sensitive brain data, protecting this information from breaches or misuse is critical.
Privacy and autonomy concerns: The passage notes worries about how neural data might be used and how technology could impact personal autonomy.
Ethical considerations: The potential for cognitive enhancement raises questions about fairness, consent, and societal impact.
Analyzing the answer choices:
(A) is correct because it directly addresses the challenges related to neural data security and privacy concerns mentioned in the passage.
(B) is incorrect; the passage states BCIs open new treatment avenues, so a lack of Option is not a challenge.
(C) is incorrect because the passage indicates cognitive enhancement potential exists, not low potential.
(D) is incorrect as the passage clearly mentions ethical considerations.
Thus, option A best reflects one of the key challenges discussed.
