Answer: C
Explanation: Let's use some background knowledge and common sense of why the answer is C. It does have a poor economy but not much rapid economic growth which is why A is out. It may have reserve in minerals but not much investment is going on like in India. D may be right about neither incredibly wealthy but most of its population which lives in its capital city of Dhaka all live below the poverty line. It is however very impoverished and densely populated. It borders east of India and was also part of Pakistan 60-50 years ago.
Hope this helps.
