A student has researched iodized salt programs and compiled the following notes:
- Iodine deficiency can cause goiter and impaired neurological development, particularly in children.
- Small amounts of iodine can be added to table salt during processing.
- Salt is widely consumed and centrally processed in many countries, making it a practical vehicle for fortification.
- Universal salt iodization programs have sharply reduced iodine deficiency in areas with high coverage.
- Excessive iodine intake can also negatively affect thyroid function.
- Public health programs must balance delivering enough iodine with separate efforts to reduce excessive sodium intake overall.

The student wants to highlight a tension public health programs must manage when using salt iodization. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Answer and explanation

Answer: C: Public health programs must balance delivering enough iodine through salt with separate efforts to reduce excessive sodium intake overall, a tension inherent in using a sodium-containing vehicle to…

The goal specifically calls for a tension, and C is the only choice that states one directly: the conflict between delivering iodine through salt and separately wanting to limit sodium intake. A describes a success without any tension. B explains a practical advantage of the delivery method, not a competing concern. D describes the health problem the program solves, not a tension in solving it.
