An observation is a. a possible explanation for events using prior knowledge b. always quantitative c. made using any of the five senses d. always qualitative

Hey there!

The correct answer to your question is option C.

An observation is made using any of the five senses.
Observations can be made whether we use our mouth, (for example, we taste something to predict what it tastes like) our nose, (we can use to observe  the smell of something) our ears, (we can use to observe what something sounds like such as a song), our hands, ( we can use to observe what something feels like), and our eyes ( we can observe to see what something looks like.)

Hope this helps you.
Have a great day!
