Final answer:

Using the Devine formula, JS's Ideal Body Weight (IBW) would be 77.6 kg or 171.03 lbs, which does not match any of the provided options.

Step-by-step explanation:

To calculate JS's Ideal Body Weight (IBW), we can use the Devine formula for men: IBW (in kg) = 50 kg + 2.3 kg per inch over 5 feet. Since JS is 6 feet tall, which is 12 inches over 5 feet, his IBW would be calculated as follows: 50 kg + (2.3 kg × 12) = 50 kg + 27.6 kg = 77.6 kg.

To convert this into pounds, we use the conversion factor that 1 kg = 2.20462 lbs. Therefore, his IBW is 77.6 kg × 2.20462 = 171.03 lbs, which is not an exact match to any of the options provided. Thus, there may be a need to re-evaluate the options given or the method for calculating IBW.

The ideal body weight (IBW) for an individual depends on various factors including sex, age, height, and muscle mass. One commonly used method to estimate IBW is the Devine formula, which calculates IBW in pounds using the following formula: Ideal body weight (in pounds) = 106 + 6 * (height in feet - 5).

In this case, JS is 6 feet tall, so his IBW would be 106 + 6 * (6 - 5) = 112 pounds. To convert this to kilograms, we divide by 2.2046 (since there are 2.2046 pounds in a kilogram), which gives us an IBW of approximately 51 kg.

Therefore answer is c) 207 lbs, 94 kg
