Answer 1

The correct option is A Mutations are always harmful to the organism.

Mutations are inheritable changes that take place in the organisms. Tse can be somatic or genetic mutations.

Genetic mutations are the changes in the genetic material of the organism that leads to various abnormalities in the organisms. These can be inherited from the organism to the future generations. Sometimes these mutations are beneficial as in cases of natural selection. When any mutation takes place in the organism it can lead to changes in the organism and they can survive better in the surrounding.

So, the correct option is 'Mutations are always harmful to the organism.'
