Which of the following is an example of an observation? a. sunsets are pretty. b. dogs like bones. c. earthquakes are bad. d. plants growth increases in the spring

The correct answer is D. Plants growth increases in the spring.

This is because observations must be objective, meaning that all people would state the same idea. This is not true for options like A and B, which are popular opinions, but definitely could be argued opinionatedly rather than with evidence that could support option D.

Hope this helps!
