Verified step by step guidance

Understand the context of the problem: Reflexes are automatic responses to stimuli that help protect the body and maintain homeostasis. In this case, we are focusing on reflexes that help maintain balance.

Identify the reflexes listed: The problem provides several types of reflexes, including deep tendon reflexes, abdominal reflexes, withdrawal reflexes, superficial reflexes, and crossed extensor reflexes.

Consider the function of each reflex: Deep tendon reflexes involve muscle contraction in response to stretching, abdominal reflexes involve contraction of abdominal muscles, withdrawal reflexes involve pulling away from a painful stimulus, and superficial reflexes involve skin stimulation. Crossed extensor reflexes are involved in maintaining balance.

Focus on the role of crossed extensor reflexes: This reflex is crucial for balance, especially in weight-bearing limbs. When one limb withdraws from a painful stimulus, the opposite limb extends to support the body's weight, maintaining balance.

Conclude that the crossed extensor reflex is the correct answer: Given its role in balance and coordination, particularly in weight-bearing situations, the crossed extensor reflex is the reflex that accompanies the flexor reflex to maintain balance.
