Well, the first one is incorrect because mutations are not one of the many things that causes evolution, as evolution is change over time. The second statement is wrong due to the fact that evolution is change over time, evolution does not happen overtime. Not all mutations are harmful, some can be beneficial and others can be neutral. The fourth statement is the correct answer, as I have said before evolution is change over a long period of time.

The correct answer is Option D

Evolution can be defined as the inheritable change that takes place over successive generations.These characters are the expressions of the gene that are passed on from one generation to another generation over a period of time. This is due to variation which comes due to recombination during sexual reproduction. This change is visible both phenotipically and genotypically.

Hence, Evolution happens slowly over a period of time.
