Having been delayed by heavy traffic, the manager arrived late for the important meeting, which caused a ripple effect on the day's schedule. Which of the following options best corrects the underlined portion?

✓ Correct Answer: Option D

The introductory participial phrase "Having been delayed by heavy traffic" correctly modifies "the manager." The original's "which" ambiguously refers to "meeting" or the entire clause. "causing" clearly modifies the manager's late arrival.
