Show answer & explanation
Correct answer: C
Concept: In this type of verbal analogy, the first pair links a physical quantity to its SI (International System) unit of measurement. To complete the analogy, the second pair must follow the exact same quantity-to-unit relationship.
Application: The given pair is Luminous intensity : Candela, since candela is the SI unit of luminous intensity. Applying the same relationship to the second term, Pressure, requires identifying the SI unit of pressure, which is the pascal.
Cross-check: Checking the remaining quantity-unit pairs confirms none of them fit the analogy:
Radian is the SI unit of plane angle, not pressure.
Newton is the SI unit of force, not pressure.
Joule is the SI unit of energy, not pressure.
Pascal is the only offered unit that matches pressure, completing the analogy.
