To be effective, an exercise program must be uniquely tailored to every person. The correct option is A.

Explanation:

Exercise is defined as a physical activity performed in different ways by an individual to increase physical fitness. An exercise program is being structured according to the specific needs of the individual performing them. This is so to yield an effective result.

While developing an exercise plan, it should be balanced as there is no single type of exercise that can take care of all the needs of an individual. This can be accomplished by creating a balanced routine to meet an immediate need. For example an individual that has the desire to lose some weight, an elderly patient with cardiac condition or a patient recovering from fractured bone. They have different health challenges and for them to achieve an effective result, their exercise program must be tailored according to their needs.
