(B) Neptune
(C) Saturn
(D) Venus
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) and (D) only
Only two planets of the solar system have no natural satellite (moon): Mercury and Venus, the two planets closest to the Sun.
(A) Mercury — no moon. It is the planet nearest the Sun, and the Sun’s strong pull makes it hard for a small body to stay in orbit round it.
(B) Neptune — has moons; the largest, Triton, goes round it in the direction opposite to Neptune’s spin.
(C) Saturn — has a very large number of moons, Titan being the biggest.
(D) Venus — no moon, like Mercury.
