The hypothesis about the possibility of planets parallel to the Earth gets its strength from the fact that

  • A.the scientists have discovered them
  • B.books have been written about them
  • C.the planetary system exists
  • D.many people have shown interest in it

Answer: C

The hypothesis gets its strength from the fact that the planetary system exists.

The author says that 'if planetary systems are common as they seem to be', planets with Earth-like conditions are possible. So the case rests on planetary systems being common, which is the existence of planetary systems.

No planet like the Earth is said to have been discovered, so A is wrong. The stories written about such planets and the interest of many people are only what prompts the question, and the passage does not treat them as evidence.
