The American College of Sports Medicine (ACSM) now does not create the physical guidelines of their own instead produces the guidelines produced by the Physical Activity Guidelines for Americans.
The guidelines are different for different age groups and for the adults which is the group which likes doing physical training, the guidelines suggest that a person should do either 2.30 hours to 5 hours of the moderate exercise per week or 75 minutes to 150 minutes vigorous exercise per week.
In the given question, the most suitable option which follows the guideline of the ACSM is option-A.
Thus, Option-A is the correct answer.

Answer:
tympanic cavity .. The primary function of the tympanic cavity is to offset the decrease in acoustic energy that would occur if the low impedance ear canal air directly contacted the high-impedance cochlear fluid.
Explanation:
Chemical features like 3 dimensional structure and chemical bonding are responsible for diversity in biomolecules although they are made from simple monomers.
In the case of carbohydrates, both starch and glycogen are made up of glucose monomers yet they differ in the functions which they perform in our body. This difference is because of the chemical bonding and the 3 dimensional structure.
Similarly in protein biomolecules, amino acids act as the monomers but they differ in function due to their 3 dimensional structure. Nucleotides are the building blocks of both RNA and DNA. RNA and DNA perform different functions in the body. DNA stores ad transfers genetic information while RNA is responsible for directly coding for amino acids.
