Best state of learning is

The correct answer is moderate arousal, no fear.

Explanation:

According to principles of educational psychology and the Yerkes-Dodson law, optimal learning and cognitive performance occur at an optimal or moderate level of arousal. When arousal is too low, a learner may experience boredom or lack of motivation. Conversely, high fear or extreme anxiety hinders cognitive processing, working memory, and focus.

Therefore, a state of moderate arousal combined with no fear creates an ideal psychological environment where students are alert, engaged, and motivated without being overwhelmed by fear or stress.
