A diligent person is

• A. Lazy
• B. Steady, hard-working, and careful in one's work or duties; industrious; painstaking
• C. Careless
• D. Reckless

Answer: (B)

Diligent describes someone who puts steady, careful effort into their work. A diligent person is steady, hard-working, and careful in one's work or duties; industrious; painstaking. This fits the idea of paying attention to detail and sticking with tasks until they’re finished. The other terms describe the opposite or lack of care: lazy is the opposite of diligent, careless means not paying attention to details, and reckless involves taking unnecessary risks without regard to consequences. For example, you could say, She is diligent in her studies, reviewing material carefully and meeting deadlines.
