What is an advantage that a lineage species concept has over the biological species concept?

A) Only a lineage species concept can be applied to cryptic species.
B) The biological species concept cannot be applied to sexually dimorphic species.
C) A lineage species concept can be applied to fossil specimens that span a large evolutionary time scale.
D) The biological species concept is difficult to apply when changing environmental conditions affect morphology.
E) The biological species concept emphasizes reproductive isolation,a property that is irrelevant to maintaining the morphological distinctiveness of most species.
