Explanation:

- Unequal distribution of assets: Wealth and resources are concentrated in the hands of a few, making it difficult to uplift the economically weaker sections. This disparity limits opportunities for a wider group of people to break the cycle of poverty.

- Improper implementation of the programmes: Even well-designed programs can fail if they are poorly executed. Issues such as bureaucratic delays and corruption can severely hinder the effectiveness of poverty alleviation efforts.

- Lack of resources: Insufficient funding, infrastructure, and manpower can constrain efforts to alleviate poverty. Limited resources make it challenging to reach all those in need and implement comprehensive plans.

- All of the above: Each of these factors contributes to the unsatisfactory results of poverty alleviation programs, and they often interrelate, compounding the problem.
