It's B

b 18 to 25

Determining the exact age range for optimum physical health can be subjective and may vary for individuals. However, in general, most sources suggest that optimum physical health usually occurs during younger adulthood.

Between the given options, option b. between the ages of 18 and 25, is commonly considered as the prime time for physical health. This is because during this age range, individuals are typically in their developmental prime, having reached full physical maturity but not yet experiencing significant declines associated with aging.

Option c. between the ages of 25 and 40 is also a reasonable choice, as many individuals continue to maintain good physical health during this period. However, some studies indicate that certain aspects of physical health, such as muscle mass and metabolism, may start to decline gradually after the age of 30.

On the other hand, option d. between the ages of 40 and 55 may not be the best choice for optimum physical health. While individuals in their 40s and 50s can still maintain good health through healthy habits, the aging process often brings about certain physical changes and potential health challenges.

In conclusion, the most accurate answer would be option b. between the ages of 18 and 25, as it aligns with the typical period of prime physical health for individuals. However, it's important to note that maintaining good physical health throughout life is a lifelong journey that involves various factors such as lifestyle choices, genetics, and overall well-being.
