Solution

The correct option is B

(d) An instrument for the blind people to guide them directions.


Scientists have created Encephalophone, a hands-free musical instrument that allows people to play music with their thoughts.

Encephalophone is based on brain-computer interfaces using an old method, called electroencephalography, which measures electrical signals in the brain.

It collects brain signals through a cap that transforms specific signals into musical notes.

It is coupled with a synthesiser, allowing the user to create music using a wide variety of instrumental sounds.

Significance:

This instrument may be used to rehabilitate patients with motor disabilities such as stroke, spinal cord injury and amputation.
