To identify the odd word from the given alternatives, we need to assess the professions listed. The options are: (A) Neurologist, (B) Dentist, (C) Architect, and (D) Paediatrician. Let's analyze each one:

• Neurologist: A medical specialist focused on disorders of the nervous system.
• Dentist: A healthcare professional specializing in oral health and teeth.
• Architect: A professional involved in designing and constructing buildings, not related to healthcare.
• Paediatrician: A doctor who manages the health of children, including physical, behavior, and mental health issues.

Upon examination, options (A), (B), and (D) are all healthcare-related professions, each specializing in different aspects of medicine or patient care. However, option (C) - Architect - is related to building design and construction, not medicine.

Thus, the odd one out is C) Architect, as it does not belong to the healthcare profession unlike the others.
