Ais the situation or setting within which all communication occurs. a. grapevine b. stimulus c. memorandum d. context

I believe the answer is: D. context

For example, let's take a look at this sentence

'you are so stupid!'

Now imagine that sentence being done in two situations;

1. when two close friends is laughing and hugging each other.

2. When a teacher scream that sentence to a student.

These 2 scenarios are what considered as context, which might influence how we perceive the message even though both have the same sentence.
