For which if any of these body areas is 99.6 degrees F. a normal temperatur?

A body temperature of 99.6 degrees Fahrenheit is considered normal for the rectal area, where temperatures tend to be higher than other measurement sites. However, it is slightly elevated compared to the typical oral temperature range, which is generally around 97.6 to 98.6 degrees F. For axillary (underarm) measurements, a normal temperature is usually lower, around 96.6 to 98.0 degrees F. Thus, 99.6 degrees F. is generally considered elevated for oral and axillary readings but within normal limits for rectal measurements.
