Examine the Following Table of Characters in Four Different Species

Examine the following table of characters in four different species of flower. Based on the matrix, Derek concludes that species A is sister to the remaining three species. Wilma, in contrast, argues that species D is sister to all other species. Who is CORRECT? $$\begin{array} { | l | c | c | c | c | } \hline & \text { Species A } & \text { Species B } & \text { Species C } & \text { Species D } \\\hline \begin{array} { l } \text { Presence of } \\\text { sepals }\end{array} & \text { yes } & \text { yes } & \text { yes } & \text { no } \\\hline \begin{array} { l } \text { Number of } \\\text { petals }\end{array} & \text { five } & \text { five } & \text { ten } & \text { ten } \\\hline \begin{array} { l } \text { Arrangement of } \\\text { petals }\end{array} & \text { whorled } & \text { whorled } & \text { whorled } & \text { whorled } \\\hline \begin{array} { l } \text { Number of } \\\text { carpels }\end{array} & \text { ten } & \text { ten } & \text { ten } & \text { five } \\\hline\end{array}$$

A) Derek is correct, as the tree that puts A as sister to all other species is the most parsimonious.
B) Wilma is correct, as the tree that puts D as sister to all other species is the most parsimonious.
C) Neither, because the most parsimonious tree puts species B as sister to all others.
D) We can't decide from the information given as trees with species A, B, or D as sister to all other species are equally parsimonious.
