Which of the following is a pull factor for migration?

Availability of many private and government offices.

The correct answer is Option (4) → Availability of many private and government offices.

• Pull factors attract people to a new place, such as better job opportunities, education, healthcare, or living conditions.

• Availability of many private and government offices means more employment opportunities, which attracts migrants.

• Occurrence of landslides, severe drought, and political instability are push factors that drive people away from their place of origin.

Thus, the pull factor here is availability of many private and government offices.
