Answer:
The correct answer is option A. "Advantageous alleles do not arise on demand".

This is wrong, evolution is the product of nature selecting random mutations that are advantageous to a species.
Answer/Explanation:
Yes, hypothesis can be proven true. A hypothesis is an educated guess that has an explanation, and you can look into it more to find if it is true or not.
For example,

Hope that helps and have a great day!
