c
Natural selection perpares the body of organisms so that in the future the vestigial structures may be used
d
The structure was probably functional in some ancestor of the modern organism

The correct answer is:
**d** The structure was probably functional in some ancestor of the modern organism.
Vestigial structures are remnants of features that served a function in the organism's ancestors but are no longer used or are greatly reduced in function in the modern organism. Their presence provides evidence of evolutionary history and the changes that have occurred over time.
