The most common cause of failure to thrive is typically nonorganic, so your answer of B is correct. Failure to thrive refers to impaired growth and development in infants and young children. It is usually attributed to nonorganic causes, such as inadequate nutrition, poor feeding habits, emotional stress, neglect, or a lack of stimulation. However, it is important to note that in certain cases, organic causes (such as underlying medical conditions or genetic disorders) may also contribute to failure to thrive. Therefore, it is important to thoroughly assess and evaluate the individual situation to determine the exact cause.
