Which of the following is not an emotion ?

Correct option is A

Memory is not an emotion. Memory refers to the ability to encode, store, and retrieve information from past experiences. It is a cognitive process rather than an emotional state. Memories can be associated with emotions, but memory itself is not an emotion.
On the other hand, emotions are complex psychological and physiological states that are typically triggered by specific stimuli or events. Emotions involve subjective feelings, physiological changes, and often lead to behavioral responses. Anger, love, and fear are examples of emotions.
Anger is a strong feeling of displeasure, usually in response to perceived injustice or provocation. Love is a deep affection and attachment towards someone or something. Fear is an emotional response to a perceived threat or danger.
In summary, memory is not an emotion but a cognitive process, whereas anger, love, and fear are all emotions.
