Why is our country regarded as the common flower garden of all castes

Because (Nepal) it is a multi-faceted society

Explanation:

It is believed that the question is directing at NEPAL.

Nepal is a country in South Asia. Naturally, the country is multifaceted, as it has various ethnic groups, language differences, various religions, etc.

However, despite so many differences in sociocultural elements, Nepal is known to be free of religious or sociocultural tension, thereby making the people regard the country as the " common flower garden of all castes."

Hence, in this case, the correct answer is " because Nepal is a multifaceted economy."
