Answer

Brief Explanations:

  • Option A: Somatic mutations don't exist in all body cells; they occur in specific somatic cells, so A is false.
  • Option B: Somatic mutations can be acquired by exposure to mutagens (like radiation, chemicals) that damage DNA in somatic cells, so B is true.
  • Option C: Inherited mutations come via germ cells (sperm/egg), somatic mutations aren't inherited this way, so C is false.
  • Option D: Somatic mutations aren't passed to offspring as they're in non - germ cells, so D is false.

Answer:

B. They are acquired through exposure to mutagens.
