A terrestrial being can never be immortal.

abnormal
marvellous
amphibious
celestial

The correct answer is D. celestial.

A terrestrial being is a living organism that lives on Earth. Earth is a planet in the solar system, which is a system of planets that orbit the Sun.

The Sun is a star, which is a giant ball of hot gas. Stars are not immortal, and they will eventually die. When a star dies, it can explode in a supernova, or it can collapse into a black hole.

A celestial being is a living organism that lives in space. Space is the vast emptiness that surrounds Earth and the other planets in the solar system. Space is filled with stars, planets, galaxies, and other objects. Celestial beings are not subject to the same laws of physics as terrestrial beings, and they may be immortal.

The other options are incorrect because they are not relevant to the question.

  • A. abnormal means “not normal” or “irregular”. This does not have anything to do with whether or not a being can be immortal.
  • B. marvellous means “wonderful” or “amazing”. This does not have anything to do with whether or not a being can be immortal.
  • C. amphibious means “able to live both on land and in water”. This does not have anything to do with whether or not a being can be immortal.
