Planet_A orbits a larger star and has a shorter orbital period compared to Planet_B. The key factors influencing transit probability include the size of the star and the orbital period of the planet. Given that Planet_A orbits a star with a larger radius and has a shorter period, it is more likely to transit, making it the better candidate for observation to maximize the chances of detecting a transit."}
