Statement B identifies the central idea of the text.
<u>Explanation</u>:
Statement B is true because babies can't communicate easily. They will take some days to communicate. They will express their feelings through crying and giving their voice loudly.
So they can't communicate very easily. Due to their inability to communicate, it is impossible to determine their true motivations for kindness. Babies cannot express their feelings easily.
If they want anything means they will cry. If they are in hunger also they will cry. So shouting and crying is the only thing that babies can do.
