'Doctor' is related to 'Patient', in the same way \( \begin{array}{ll}\text { (a) Customer } & \text { (b) Criminal } \\ \text { (c) Magistrate } & \text { (d) Client }\end{array} \)

A doctor provides care and treatment to a patient, establishing a direct relationship based on professional health services. Similarly, a client seeks advice and services from a magistrate, who is a judicial officer overseeing legal matters and cases. This forms a supportive connection where the magistrate helps clients navigate legal issues, akin to how doctors guide patients through health concerns. On the flip side, a customer engages with a seller or service provider but doesn't have the specialized care relationship that doctors and patients share. A criminal, while being part of a legal relationship, is more of a subject of judicial action rather than the one receiving guidance or support. Therefore, the correct analogy here is between the magistrate and the client!
