Answer:

A dichotomous key involves two options.

Explanation:

Dichotomous keys are a type of identification key and are tools that allow the identification of the names of taxonomic groups belonging to a group of organisms, usually in a certain geographic or ecological region. Through systematic descriptions, this type of key works by offering two options in each step and choosing one of them determines the next step.

The use of identification keys leads the user to know not only the different characteristics of the species, but also helps to understand the reasoning used in the classification of these species.
