Answer:
the use of an incorrect communication medium
Step-by-step explanation:
In this scenario the supervisor keeps disrupting Clarissa's work by speaking with her and asking trivial questions.
If the supervisor uses the email instead of verbally asking questions this will remove distractions Clarissa is having in her work.
This depicts use of incorrect medium of communication.
When a wrong medium is used to communicate it causes inefficient delivery of the message and can even cause the recipient to not respond.
For example if instructions are to be given to staff for immediate implementation, the most effective way is to set up a meeting feedback can be gotten. This ensures all challenges to implementation are dealt with.
If however the instructions are placed on a notice board, some employees may not read them.
