Contemporary most closely means:

• A. Modern
• B. Ancient
• C. Outdated
• D. From or existing in the same time period

Answer: (D)

The word is about time relationship. Contemporary means from or existing in the same time period as something else. That makes the option describing being from or existing in the same time period the best fit, because it pins the meaning to a shared era or lifespan.

Context helps: contemporary can also be used to mean present-day or modern in everyday usage, but the strongest, most precise sense when comparing one thing to another is the time-frame relationship—they originated or exist together in the same period.

Ancient and outdated describe things from the distant past or no longer current, which is opposite. Modern can be close in meaning, but it shifts toward present-day styles or conditions rather than strictly the same historical time frame.
