The answer is letter B.
People
who have troubles in sleeping are usually the ones who are under a lot of
stress. Too much anxiety can cause the brain to overthink situations that are
yet to come which then causes a restless state leading to a lack of sleep.
Often times, people who lack sleep end up getting easily frustrated and most of
the time get easily annoyed. To get out of this, one should practice at least
10 minutes of complete silence to reflect on things followed by deep breathing.
This calms the mind and it helps it to shift the attention of a person putting
him/her into a relaxed sleepy state.
