Please help me with these multiple choice biology questions

Is it more likely that the "ancestral lizard" had legs or was limbless? a. It was probably legless because having legs is a derived characteristic b. t probably had legs because most reptiles today have legs and it requires fewer evolutionary changes to get the three modern groups of limbed reptiles and two groups of limbless reptiles than if we start with a limbless ancestor. c. It was probably legless because that is the most parsimonious explanation d. It probably had legs because Geckos (the bottom group of the five) are the oldest group and they have legs.

Explanation / Answer
