Verified step by step guidance

Understand the concept of reflexes: Reflexes are automatic, involuntary responses to stimuli. They can be categorized into intrinsic (innate) reflexes and learned (acquired) reflexes.

Define intrinsic reflexes: Intrinsic reflexes are those that are naturally present at birth and do not require learning or practice. They are hardwired into the nervous system.

Identify examples of intrinsic reflexes: Common examples include the knee-jerk reflex, withdrawal reflex, and the reflexes involved in maintaining posture.

Analyze the options given: Singing a song, playing a musical instrument, and driving a car are activities that require learning and practice, thus they are not intrinsic reflexes.

Conclude with the correct example: Maintaining posture is an intrinsic reflex because it involves automatic adjustments by the body to maintain balance and posture without conscious effort.
