The answer is the second option or B, <u><em>"Classification systems have become more complex to allow for all the discoveries made about organisms."</em></u>
Classification systems were created with the purpose of classifying living things such as plants, animals, species in general. It gathers lots of information about a species and it includes the spercies name, its genus, family, relatives, order, class, kingdom, among others.
One of the reasons why classification systems have become more complex to allow for all the discoveries made about organisms is because scientists are finding new information about the species or they interpret facts in different ways from how they did at first.
A true fact about that is that in the 1700s, classification systems were based on morphological characteristics of the species or organisim, later, now in the present it changed radically with the DNA tests made to organism. It is providing new information and it kind of forced the system to update.
