Brain drain refers to:

Brain drain refers to:

• A. The emigration of unskilled workers
• B. The emigration of skilled workers
• C. The immigration of skilled workers
• D. The return of workers from abroad

Answer: (B)

Brain drain describes the loss of highly skilled workers from one country to another, usually to wealthier nations, in search of better pay, opportunities, or working conditions. This is best understood as the emigration of skilled workers— professionals such as doctors, engineers, scientists leaving their home country. The other scenarios describe different movements: the departure of unskilled workers isn’t focused on skill levels; immigration of skilled workers is the inflow to a country rather than an outflow; and the return of workers from abroad refers to people coming back, not leaving. The key idea is the outflow of educated, trained individuals who can drive a country’s development but choose to work elsewhere.
