Answer:
The correct answer is "kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin".
Step-by-step explanation:
Kin recognition, also known as kin detection, is an ability developed by some animals to detect organisms that are genetic related and discriminate among other animals that are not (nonkin). There are some mechanisms that animals use for kin recognition, however labeling actively each other is not one of them. In most cases, animals use kin recognition based on pheromonal cues.
