Answer:
B. Objective
Step-by-step explanation:
The word “objective” refers to factual, data-based information that is not informed by bias. When someone gives you an objective assessment of a topic, it is formulated from data, verifiable facts, or other irrefutable evidence without considering the speaker’s personal feelings.
This article states that a census update recorded that China had the highest population in the world. A census cannot be subjective, which means "a term that refers to someone’s personal opinions or feelings regarding a particular subject matter."
