Final answer:
Autonomy in the context of psychological needs of SDT refers to the need for choice and self-determination. (Option 3)
Step-by-step explanation:
In the context of the Self-Determination Theory (SDT) developed by Deci and Ryan, autonomy refers to the psychological need for choice and self-determination. It involves the desire to have control over one's actions and make decisions that align with one's values and interests.
Autonomy is one of the three fundamental psychological needs proposed by SDT, with the other two being competence (the need for mastery) and relatedness (the need for connection with others). Autonomy is associated with a sense of agency and the ability to act in accordance with one's own will, which is considered essential for promoting intrinsic motivation and well-being.
Therefore, the correct option is 3) The need for choice and self-determination.
