Detailed explanation-1: -Of the inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos.
Detailed explanation-2: -Venus and the planet Mercury are the only two planets that don’t have a single natural moon orbiting them. Hence, Option 1 is correct. Mercury is the first planet from the sun in the solar system as well as the smallest planet among the eight planets.
Detailed explanation-3: -Abstract. The possibility that Mercury might once have been satellite of a Venus, suggested by a number of anomalies, is investigated by a series of numerical computer experiments. Tidal interaction between Mercury and Venus would result in the escape of Mercury into a solar orbit.
