The correct answer is Option D.
To communicate effectively, you must be able to read, write, speak and listen properly.
This is because communication simply means the transfer of information. There are different types of communication such as verbal and non-verbal communication.
For verbal communication to happen it requires the ability to listen and then respond and hence for verbal communication to take place effectively the person must speak and listen properly.
On the other hand for Non-verbal communication to take place it requires the ability to read and write. So both the sender as well as the receiver must have the ability to read and write properly in order to take place the communication effectively.
