Explanation:
The plants are competing against each other for the resources they need for survival. The other three answers involve different plants interacting with each other and the question does not mention interactions between them, meaning it's basically referring to survival of the fittest.

The planet is close to its sun the way Mercury is close to the sun in our solar system.
Explanation:
Solar system consists of the Sun and the eight planets, dozens of moons, asteroids,comets, meteoroids. The names of the eight planets includes:
-- Mercury
-- Venus
-- Earth
-- Mars
-- Jupiter
-- Saturn
-- Uranus and
-- Neptune.
Mercury is a rocky planet with a thin atmosphere. It is the smallest terrestrial planet and the closest to the sun. It is said to have a thin atmosphere because it lacks hydrogen. The atmosphere gets thinner as one moves further away from the planets surface.
Mercury is a rocky dense planet because its composed mainly of iron and nickel with an iron core. It is also covered by a thin layer of tiny particle silicates.
Therefore the rocky planet with a thin atmosphere identified by the scientist must be a planet that is close to its sun the way Mercury is close to the sun in our solar system.
