Verified Correct Answer: D.
Step-by-Step Mathematical Solution
The median weight is the weight value corresponding to the 50th worker in this group of 100 (since the median is at the midpoint). On a cumulative frequency curve, draw a horizontal line from 50 on the y-axis to intersect the curve (likely at R), then drop a vertical line to the x-axis (weight), landing at Q. Thus, point Q indicates the median weight.
