    Answer:

    The correct answer is option b. “streamlined bodies in dolphins and ichthyosaurs”.

    Explanation:

    An homoplasy is defined as a trait that is shared between two different species but that they do not originate from a common ancestor. An example of homoplasy is the streamlined bodies in dolphins and ichthyosaurs. Ichthyosaurs were reptiles, not mammals like modern dolphins, therefore their similar streamlined bodies evolved separately.
