'Vendor' is related to 'Buyer' as the service-provider/seller is to the recipient. In the same way, a 'Consultant' is related to which counterpart?

Introduction / Context:
The relation is provider ↔ recipient. A vendor sells to a buyer. A consultant provides professional services to a client. We must pick the standard counterpart in a consulting engagement.

Given Data / Assumptions:
Consulting arrangements use “client” as the recipient party.

Concept / Approach:
Match the transactional roles (seller→buyer :: consultant→client).

Step-by-Step Solution:

Verification / Alternative check:
“Firm” could employ consultants, but is not the generic recipient term. “Advice”/“Consult” are actions, not counterpart roles; “Employer” is a distinct employment relation.

Why Other Options Are Wrong:
They do not name the counterpart role in the service exchange.

Common Pitfalls:
Confusing the hiring entity with the role name used in professional services contracts (“client”).

Final Answer:
Client
