3. [bws.02] which of these is an example of a hypothesis? observe a plant kept in the dark wonder why plants grow well in sunlight leaves may change color due to temperature add different quantities of water to three potted plants

Option C, Leaves may change color due to temperature

Explanation:

Hypothesis is basically an assumption which is then examined based on practical grounds and can be proven false or true with logical consequences.  

Here, the assumption “leaves may change color due to temperature” is an assumption which can be tried and tested for establishing its ethnicity.  

While all other statements such as “observe a plant kept in the dark” and “add different quantities of water to three potted plants “ are  simple statements  in which something is being done/or asked to be done. While in statement “add different quantities of water to three potted plants” is a question about a pre established fact and hence it cannot be considered as an assumption.

Thus, option C is correct.
