## QuestionClass 10

Consider the following pairs:
$$1$$. Mercury: Jovian plant
$$2$$. Venus: Duration of day longer than that of year
$$3$$. Satum: A planet having density less than that of water
Which of the pairs given is/are correctly matched?

(A) $$1$$ only
(B) $$2$$ and $$3$$ only
(C) $$1$$ and $$3$$ only
(D) $$1, 2$$ and $$3$$

Mercury is not a Jovian planet but inner or terrestrial planet. Jovian means Jupiter- like(the largest planet of the solar system), with an equatorial diameter of just48754875km, Mercury is the smallest planet of the solar system.
Venus has rotation period of243243days(duration of day) and revolution period around the sun of224.4224.4days(duration of the year). Thus the planet Venus has duration of day longer than that of year.
Saturn has density of0.690.69which is less than the of water(1.0)(1.0).
