The correct answer is C. The Spenodontia are sister taxa to squamata.

Explanation:

Spenodontia is an order of reptiles that were numerous during the Mesozoic Era, but today include only one living genus: Sphenodon, popularly known as tuatara, which lives in New Zealand.

The animals of this order are not lizards, but close relatives of these. The order Spenodontia forms, along with the order Squamata (lizards), the superorder Lepidosauria.
