The factor that is primarily impeding economic growth in India from the options provided is poor infrastructure. While India has a rapidly growing economy, inadequate infrastructure, such as roads, transportation, and utilities, can hinder economic development and efficiency.
- It's command economy: India is actually a mixed economy with both market and command elements, but it is not primarily a command economy.
- Microlending: This often promotes economic growth by providing loans to those who might not have access to traditional banking.
- Outsourcing: While it has its challenges, outsourcing has also created many jobs and has been a significant factor in India's economic growth.
So, the correct answer is Poor infrastructure.
