The O = 16 scale became the standard in 1903 and carbon-12 was chosen in 1961.
The answer is B. Because think about it, it’s not a scientific fact that brown dogs are better pets, and the best color for your room isn’t it because the answer would be an opinion of someone not a fact. I hope this might help you.
