Let's analyze each statement regarding the homeopathic remedy *Carcinosinum*:
Statement I: Carcinosin is indicated in post operative gas pains, no relief from passing it.
While *Carcinosinum* can be used for a wide range of complaints, including gastrointestinal issues, it is not a primary or specifically well-known remedy for post-operative gas pains that are unrelieved by passing flatus. Other remedies like *Nux vomica*, *Carbo vegetabilis*, or *Colocynthis* are more typically considered for such symptoms. Therefore, Statement I is likely incorrect.
Statement II: Children have great fear, are sensitive to reprimands but sympathetic to others is a characteristic feature of Carcinosin.
This statement accurately reflects key emotional and behavioral characteristics often associated with the *Carcinosinum* type, particularly in children. They can exhibit deep-seated fears, be very sensitive to criticism or reprimands, and yet possess a strong sense of empathy and sympathy towards others. This combination of sensitivity and compassion is a notable aspect of the *Carcinosinum* personality. Therefore, Statement II is correct.
In conclusion, Statement I is incorrect, but Statement II is correct.
