Which definition best matches 'robust'?

• A. healthy
• B. hardy or strong
• C. sturdy and able to withstand detrimental conditions
• D. successful

Answer: (D)

Robust centers on strength, resilience, and the ability to keep going under stress. The best match is the definition that describes being sturdy and able to withstand detrimental conditions. That phrasing captures both durable physical strength and the capacity to endure adverse situations without breaking down, which is exactly what “robust” conveys in most contexts—from healthy bodies to sturdy equipment or resilient systems.

While healthy or hardy/strong touch on parts of the idea, and being healthy can be described as robust in some cases, the strongest sense of robustness is the capacity to resist damage and continue functioning under pressure. Being successful isn’t the core meaning of robust; robustness is about durability and resilience, which can contribute to success but isn’t the same as achieving it.
