To answer the question, let's analyze each option:

1. Emotion: Emotions are complex psychological states that involve three distinct components: a subjective experience, a physiological response, and a behavioral or expressive response. Sucking in infants is not primarily driven by an emotional state.

2. Habit: A habit is a routine behavior that is repeated regularly and tends to occur subconsciously. Habits are usually formed over time through repetition. Since sucking is an innate behavior present from birth, it is not considered a habit.
