Due to a testing delay, release of the product for manufacture is delayed by 5...

 Situation Analysis:

A 5-day delay in product release impacts the printing window.

The printer is further delayed by 10 workdays.

 Total Delay Impact Calculation:

The combined impact of the testing and printing delays = 5 + 10 = 15 days.

This results in a cumulative delay in product release.

 Cross-Verification:

Option B: Incorrect. Ignores delays entirely.

Option C: Incorrect. Assumes only one source of delay.

Option D: Incorrect. Underestimates delay impact.

Option A: Correct. Matches the calculated total delay.
