How is the ideal body weight calculated for females?

The ideal body weight for females is commonly calculated using a formula that incorporates a base weight for a standard height and an incremental increase based on additional inches beyond that height. The correct formula, which is based on a reference height of 5 feet, starts with a base weight of 45.5 kg, which represents the ideal body weight for a 5-foot-tall female.

For each additional inch above 5 feet, the weight is increased by 2.3 kg. This calculation allows for variations in body size while also accounting for the differences in body composition as height increases. The use of this formula reflects a standard practice in determining an ideal weight range that can assist healthcare professionals in clinical settings.

In contrast, the other options either start with an incorrect base weight or use an incorrect increment per inch, making them less accurate for this calculation. Therefore, choice B is recognized as the ideal method to determine the ideal body weight for females.
