An exoplanet is defined as a planet that orbits a star outside of our solar system. Over 400 exoplanets have been discovered. Some scientists have hypothesized that some of these exoplanets may contain life.

Question

 
How could ,begin emphasis,current,end emphasis, technology help determine if an exoplanet might be a suitable candidate for life?
Answer options with 4 options
A.
High-speed spacecraft could be sent to distant star systems and land on exoplanets to investigate their surfaces for life.
B.
High-powered, Earth-based telescopes could see signs of life and city lights if advanced civilizations are present.
C.
Highly-sensitive sound meters could record evidence of sound waves since exoplanets with life may produce slightly different kinds of wave energy.
D.
Highly-sensitive instruments could detect exoplanets with Earth-like orbits based on how much light from their parent stars is blocked.

Answer 1

The best answer to the question of how current technology could help determine if an exoplanet might be a suitable candidate for life is:

D. Highly-sensitive instruments could detect exoplanets with Earth-like orbits based on how much light from their parent stars is blocked.

This method, known as the transit method, involves measuring the dimming of a star's light when a planet passes in front of it. Detecting an exoplanet's size and orbit can provide valuable information about its potential habitability.
