Answer:
C) Cultural bias
Step-by-step explanation:
A cultural biased experiment is one which is based on the cultural views or perceptions. In this experiment where a scientist is trying to see whether dogs or cats are more popular, he conducted a questioning assessment from all the dog owners in a dog park.
He found that 100% (all) of them preferred dogs to cats. This preference is due to the to the culture of the dog owners who have a mentality of dogs being their best choice without exploring possibilities from other pet animals. The scientists goes to the dog park knowing that the dog owners will favour dogs over cats. Hence, it is a cultural biased experiment.
