A water flask had a very low level of water. A crow dropped pebbles in the flask to raise the water level enough so that it can drink the water.The type of learning behaviour exhibited by the crow in the given situation is

Explanation

The correct answer is insight learning. Insight learning involves solving a problem through understanding the relationships between various parts of a problem rather than through trial and error. The crow dropping pebbles into the flask to raise the water level demonstrates an understanding of cause and effect, which is characteristic of insight learning. Option A, imprinting, is incorrect because imprinting is a type of learning that occurs during a critical period and does not involve problem-solving. Option B, latent learning, is incorrect because latent learning refers to knowledge that is not immediately expressed until there is a reason to demonstrate it. The crow's behavior is immediate and not latent. Option D, conditioned reflex type I, is incorrect because a conditioned reflex is an automatic response learned through association, whereas the crow's action is an active problem-solving technique.
