Answer :
"the client may be liable for a commission and
marketing expenses".
Step-by-step explanation:
The connection between client and agency is a two-way street. All sides are giving and taking from each other, but it is through this exchange that their mutual goal of successful campaigns can be achieved.
In this case when the client feels to revoke the deal because he has liability for the agent.
so the client has revoked the deal with the agent.
