Answer: (A)

Verified step by step guidance

1. Understand the role of the endocrine system: The endocrine system is responsible for producing and regulating hormones that control various bodily functions. Disorders in this system often arise from issues with hormone production, regulation, or gland function.
2. Analyze the options provided: Evaluate each option to determine its relevance to the endocrine system. For example, dietary fiber deficiency, femur fractures, and skin infections are not directly related to hormone production or gland function.
3. Focus on the pituitary gland: The pituitary gland is a key component of the endocrine system, often referred to as the 'master gland' because it regulates other endocrine glands and hormone production. A tumor in the pituitary gland can disrupt its function, leading to hormonal imbalances and endocrine disorders.
4. Consider the mechanism of disruption: A tumor in the pituitary gland can cause overproduction or underproduction of hormones, which may lead to conditions such as acromegaly, Cushing's disease, or hypothyroidism. This makes it the most likely cause of an endocrine disorder among the options provided.
5. Conclude based on biological reasoning: Since the pituitary gland directly impacts hormone regulation, a tumor in this gland is the most plausible cause of an endocrine disorder compared to the other options, which do not directly affect the endocrine system.
