which of the following is a claim?
lizards are reptiles.
lizards make great pets.
lizards are related to dinosaurs.

Explanation:

A claim is an arguable statement based on opinion. "Lizards make great pets" is subjective (opinion - some may agree, some may not). "Lizards are reptiles" is a factual classification (not arguable as it's a biological fact). "Lizards are related to dinosaurs" is a scientific fact (based on paleontological evidence, not easily argued against in a general sense as it's a recognized scientific relationship). So only "Lizards make great pets" fits the definition of a claim.

Answer:

Lizards make great pets.
