Answer: D. Scientists have recently discovered a new exoplanet.
Answer: (d) Scientists have recently discovered a new exoplanet.
Explanation: The Present Perfect tense connects the past to the present and cannot be used with specific, finished past time markers like "last night" or "in 2024" (which require Simple Past). Option (c) requires Past Perfect. Option (d) correctly uses the indefinite time marker "recently."
