The program suggests maintaining a consistent intensity for the first 3 visits, gradually increasing intensity over the subsequent 3 visits, followed by a decrease in intensity for the next 3 visits, before repeating the pattern.

Which of the following options represent the possible intensities for Amber's exercise during the fourth, fifth, and sixth visits? Select three options.

A. 63\%, 63\%, 63\%

B. 66\%, 69\%, 72\%

C. 66\%, 62\%, 58\%

D. 63\%, 65\%, 67\%

E. 67\%, 72\%, 77\%

To solve this problem, we need to determine the exercise intensities for the fourth, fifth, and sixth visits based on the pattern described. Here's a step-by-step guide:

1. Understanding the Pattern:
- The intensity is maintained at 60% for the first three visits.
- The intensity then gradually increases over the next three visits.

2. Given Intensities:
- Visit 1: 60%
- Visit 2: 60%
- Visit 3: 60%

3. Determining the Next Visits:
- The intensity for the 4th visit should increase slightly from 60%.
- The intensity for the 5th visit should increase slightly more.
- The intensity for the 6th visit should continue to increase slightly.

4. Intensity Values:
- For the 4th visit, a reasonable small increase might be to 63%.
- For the 5th visit, it should increase a bit more to 65%.
- For the 6th visit, it could further increase to 67%.

Based on this, the exercise intensities for the fourth, fifth, and sixth visits would be:

- 4th visit: 63%
- 5th visit: 65%
- 6th visit: 67%

The correct option that matches these values is:
[tex]\[ 63\%, 65\%, 67\% \][/tex]

Therefore, the possible intensities for Amber's exercise during the fourth, fifth, and sixth visits are:

[tex]\[ 63\%, 65\%, 67\% \][/tex]
