B, because people do selective breeding to get something they want out of it. Which decreases genetic diversity, genetic diversity meaning there being less and less traits and characteristics and we wont something perfect not exactly something with traits that we dont like. However dont get me wrong, nothings perfect. But yeah.
Given = b = 20cm, A = 500cm2 l=?
A = l×b,
500= l×20
l= 25
