Q1. With reference to Brain–Computer Interfaces (BCIs), consider the following statements:
- BCIs enable direct communication between the brain and external devices.

- Signal decoding in BCIs is typically performed using AI/ML algorithms.
(a) 1, 2 and 3
(b) 1 and 3 only
(c) 2 only
(d) 2 and 3 only
Correct Answer: (b)
Explanation:
- BCIs function through neural signal acquisition → AI/ML-based decoding → device command execution.
- Non-invasive BCIs (EEG) are safer but less precise than invasive BCIs.
- Hence, statements 1 and 3 are correct.
