Answer:
The correct option is trial and error learned behavior
Explanation:
A trial and error learned behavior is a type of behavior in which an organism attempts to or tries something new which makes it (the organism) accept the reality of that thing or situation. This means that if the attempt is successful or pleasurable, the organism will attempt it again and if it's not, the organism will avoid that thing.

B. mammary glands and hair or fur. things also to classify: feed milk to young, give birth live, and breathe in air, so they have lungs.
<span>Aplysia is a marine gastropod mollusc which is an often used model organism in neuroscience, especially on the cellular biology of learning and memory. What makes them easy to work with are their giant neurons, which are one of the largest. Aplysia neurons are suitable for studies of how neurons and neural circuits control behaviours. Its defensive reflex has been studied because it is mediated by electrical synapses, which allow several neurons to fire synchronously.</span>
