a. Horizontal; informal
b. External; informal
c. Vertical; informal
d. External; formal
Is C correct answer?thank you

No, option C is not the correct answer. The correct answer is option A: Horizontal; informal.

To arrive at this answer, let's break down the question and its options:

The communication is described as being about an announcement of a company-sponsored picnic, which indicates internal communication or communication within the organization. This rules out option B, which suggests that the communication is external.

Next, we need to determine the type of communication. The fact that the announcement travels from the employees' social committee to the other employees through email implies that it is informal communication. Formal communication typically follows a structured and official hierarchy, involving channels such as memos, official reports, or formal meetings. Informal communication is more casual and occurs between peers or colleagues.

Finally, we have two options left: option A and option C. To choose between them, we need to understand the direction of the communication. The term "horizontal" refers to communication that occurs between individuals at the same hierarchical level or across different departments. In this case, the announcement travels from the employees' social committee to the other employees, indicating a horizontal direction. Therefore, option A (Horizontal; informal) is the correct choice.

Remember, when answering questions like this, it can be helpful to carefully consider the specific details provided in the question and options, and then eliminate options that do not fit the given criteria.
