Option 2 : 2 and 3 only

The correct answer is 2 only.

  • Mars has only 2 natural satellites (moons).
    • Saturn has the highest number of natural satellites i.e. 82. Hence statement 1 is not correct.
  • The inner planets are very close to the sun and they are made up of rocks. Hence statement 2 is correct.
  • Our solar system is having two types of planets: Inner planets and Outer planets.
    • Inner planets include the nearest four planets around the Sun namely Mercury, Venus, Earth, and Mars.
      • They are having a dense and rocky composition and referred to as terrestrial planets.
      • They are mostly made of iron and nickel.
      • Venus is the hottest inner planet and Mercury is the second densest after the Earth.
    • The outer planets include the last four planets of the solar system namely Jupiter, Saturn, Uranus, and Neptune.
      • They are referred to as gas giants or Jovian planets.
      • They are massive and have a gaseous composition.
      • They have a thick atmosphere mostly of helium and hydrogen.
    • Hence, statement 3 is correct.

From the above, we can conclude that statement 2 and 3 are correct.

Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count thereby reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification. In a BCD Subtractor if the sum of minuend and the nine’s complement of the subtrahend is not a valid BCD Code, then which binary number is added to the sum to get the correct answer?
