Question

pick are the collective noun used for the elephant and use it sentence in your own​

Answer 1

A group of elephants is called a herd. It is a collective noun. So if a collective noun has to be used for the elephants it will be the herd.  

The sentence with the word herd will be ‘the herd of the elephants takes the best care of the kid-elephants of their group.”  

Here both the words elephant and the herd have been used.
