Answer:
The correct answer will be option-A.
Step-by-step explanation:
A scientific consensus is a general agreement based on the opinions and judgement by the community of scientists in a particular field of study. The scientific community agrees on the same opinion which is accepted at the universal level.
In the given question, the scientist found new fossil which indicated that dinosaur posses hairs at some point of time. The scientist was not accepting this idea as it was against the scientific consensus on dinosaurs that dinosaurs have scaly skin. This indicates that the scientist was biased with the scientific consensus.
Thus, option-A is the correct answer.
