The correct choice highlights that children tend to have a lower frequency of reactions to contrast media compared to other age groups. This is primarily due to several physiological factors. For one, children often have different body compositions, metabolic rates, and immune responses that can influence how they react to medications, including contrast agents.

Additionally, children typically have less exposure to medical procedures involving contrast media than adults, which may lead to a lower incidence of previous reactions and, consequently, lower sensitivity. Infants and senior adults, on the other hand, may have more cautious profiles due to their unique vulnerabilities, often showing a higher propensity for reactions due to their developing or declining physiological states respectively.

Understanding these dynamics is crucial for healthcare professionals when preparing for imaging studies involving contrast media, as the risk profiles of different age groups vary significantly.
