China has relaxed 'One Child Norm' policy now a days due to which reason ?

More elderly people in proportion to young

 The correct answer is option (4) : More elderly people in proportion to young

The one-child policy had successfully curbed population growth in China, but over time, it led to a shrinking workforce and a rapidly aging population. This imbalance created challenges for social security systems and economic growth. One child norm and the resultant arrest in the growth of population has resulted in more elderly people in proportion to young people. This led China to allow couples to have two children. By relaxing the policy, China aims to encourage more births and achieve a more balanced population structure.
