Communication is the sending of information or news from one person to another. If human beings could not communicate with one another, each person would have to learn everything for himself. Although animals as well as men can communicate, so far as we know, they can express only the simple emotions like pain, joy, fear, hunger, anger and love. Some animals have a more advanced form of language using sounds, and others use a wide range of sounds and face movements, but we still have much to learn about these animal languages.
Speech is the most important means of communication between people. But it is not the only one. Nor is it the oldest. We use facial expressions, gestures and hand movements to express our feelings and to send signals to other people. Animals use this "body language" a great deal. The sign language used by deaf people is an example of communication without speech, while blind people communicate largely through touch and hearing.
Which of the following statement is true

A.Humans do not have adequate knowledge about animal languages.
B.We are now very much aware of animal languages.
C.Most of animals use their facial expressions,
D.All animals make sounds to communicate with each other.
