'Doctor' is related to 'Patient' as the professional who represents and advises whom? Choose the profession–counterpart pair that best parallels this relationship for a lawyer.

Introduction / Context:
Professional relationship analogies test whether you can map roles consistently. A doctor serves and treats a patient; similarly, a lawyer represents and advises a specific counterpart in legal matters. We must pick the person to whom a lawyer stands in the same service relationship.

Given Data / Assumptions:

• Doctor → Patient is a care-provider to recipient relationship.
• Lawyer provides legal counsel and advocacy.
• The parallel should preserve the “service provider → recipient” mapping.

Concept / Approach:
Translate roles: the one who seeks legal services from a lawyer is the client. Other legal system roles (magistrate, criminal) are not the recipient of the lawyer’s fiduciary duty in general; “customer” is too generic and not the precise legal term.

Step-by-Step Solution:
1) Identify how doctor and patient are related (provider → recipient).2) Map the legal equivalent: lawyer → client.3) Select “Client.”

Verification / Alternative check:
Legal ethics and practice guidelines explicitly reference “lawyer–client” relationships with duties of loyalty and confidentiality, confirming the parallel.

Why Other Options Are Wrong:

• Magistrate: An adjudicator; not the recipient of a lawyer’s services.
• Criminal: A status for some defendants; lawyers represent clients (who may be civil, criminal, corporate, etc.).
• Customer: Overly broad commercial term, not the standard legal counterpart.

Common Pitfalls:
Confusing legal system participants; focus on the direct service relationship analogous to doctor–patient.

Final Answer:
Client
