Q. Consider the following statements:
  1. Titan is the largest moon of Jupiter and is the only known moon to have a magnetic field
  2. Ganymede is the largest moon of Saturn and is the only moon to have a dense atmosphere
Which of the above statements is/are correct?

Answer: Neither 1 nor 2
Notes:
  1. "Titan is the largest moon of Jupiter and is the only known moon to have a magnetic field": This statement is incorrect on both counts. Titan is not a moon of Jupiter; it is a moon of Saturn. Titan is indeed the largest moon of Saturn and is known for having a thick atmosphere rich in nitrogen, along with lakes and rivers of liquid hydrocarbons on its surface. However, Titan does not have a significant magnetic field.
  2. "Ganymede is the largest moon of Saturn and is the only moon to have a dense atmosphere": This statement is partially correct and partially incorrect. Ganymede is not a moon of Saturn; it is a moon of Jupiter. Ganymede is indeed the largest moon in the entire solar system, and it's one of the Galilean moons of Jupiter. It is also the only moon known to have its magnetic field. However, Ganymede does not have a dense atmosphere. It has a very thin atmosphere composed mainly of oxygen, but it's not considered dense compared to Earth's atmosphere.
Correct information is as follows:
