Question

all of following urls are valid sources for information except which one should be double - checked for accuracy and information provided?.edu.org.com

Explanation:

.edu domains are tied to educational institutions, which typically have rigorous editorial standards for accuracy. .org domains are for non-profits, which often provide vetted, mission-driven information but still need checks. .com domains are commercial, focused on profit, so their information is most likely to be biased, unvetted, or inaccurate without verification, meaning it requires double-checking more critically than the others as it is the least inherently valid source category here.

Answer:

.com
