Answer: Option (A)

Explanation: According to the geological time scale, new species comes into existence suddenly and are quite fully developed. The gradual evolution of species from one kind to another is hardly seen and a very few of them were able to record in its history.

     For example, in most of the ammonoides, various step-by-step changes have been showcased but only the size and surface texture are observed to be changed.

  Thus, the correct answer is option (A).
