Candace is interested in learning more about colors. Which question about colors could be answered through scientific investigation?

you could use " Which flower has the prettiest shade of purple on its petals?"

Hi!

I believe that there were the following options in this question:

A) Which color bends the most to make a rainbow?

B) What color of scented marker has the best smell?

C) Which flower has the prettiest shade of purple on its petals?

D) What is the best-looking color on a high-performance sports car

Now, options b), c) and d) are about a personal preference and opinion - they are not scientific uqestions.

The correct answer is a) - it asks about the properties of light.
