Question

which piece of technology allowed scientists to look for life on mars? a telescope a rover a microscope probeware

Explanation:

A telescope is mainly used for observing from a distance in space but not for detailed surface exploration to look for life. A microscope is for very small - scale objects (like cells) and not for planetary surface exploration. Probeware is usually for collecting specific types of data (e.g., in a lab or on Earth - based field studies) in a more limited sense. A rover, such as the Mars rovers (e.g., Curiosity, Perseverance), is designed to move on the Martian surface, collect samples, analyze the environment (which could potentially indicate signs of life like looking for organic compounds, water - related features etc.).

Answer:

B. a rover
