1. a and b are the same tree but drawn in opposite orientation.
2. a, b, c and e share the same phylogenetic relationships. A close look into the trees reveal that the whale along with the other animal (?) form a separate group and have evolved the most.
3. In a, b, c and e, whale and camel has same the phylogenetic distance (relationship), which is not found in case of d. In a, b, c and e, camel has evolved the least and is close to the root. But in case of d, camel shares a common group with deer (?). This alters the phylogenetic distance between whale and camel.
Thus, the tree in d is different and does not indicate the same relationship between whale and other animals.
