Communication is divided into two parts; verbal and non verbal communication. The verbal communication needs words and non verbal communication needs expressions. Therefore, body language and words are usually the most significant parts of a message communicated. 

The correct answer is the second option "tone and body language".

Explanation:

When communicating a message, particularly a verbal message, both tone and body language are important.

As regards tone, they relate to verbal communication so its use is crucial to transmitting the appropriate message. When combining tone, inflection, volume, and pace of speech in the right way, you are able to sound secure and eloquent before your audience.

As regards body language, it relates to non-verbal communication and reflects what the speaker thinks, or feels when delivering a speech. That is why it is so important to have good management of gestures, hand movements, smiling, looking at the audience's eyes, etc.

making a claim is just a fancy way of saying that you're stating your main point.' claims are not just opinions. a claim tells what you think is true about a topic based on your knowledge .

about the country claims : -

a counterclaim is just the opposite of a claim. counterclaims are also provable and supportable by reasons and evidence. not just, 'because i said so.' when you're planning an argument, you need to know what the counterclaim might be so that you can make sure that you disprove it with your reasons and evidence your research." - (catherineroberts)
