To make 10 card tables, we need:

- 4 legs per table x 10 tables = 40 legs
- 1 top per table x 10 tables = 10 tops
- 2 covers per table x 10 tables = 20 covers
- 6 clamps per table x 10 tables = 60 clamps
- 13 bolts per table x 10 tables = 130 bolts

From the parts-listing matrix, we can see that each leg requires one rod. Therefore, we need:

- 40 legs x 1 rod per leg = 40 rods

Each top requires four rods for the frame, and we have 10 tops. Therefore, we need:

- 10 tops x 4 rods per top = 40 rods

Lastly, we need to add up the number of covers, clamps, and bolts required:

- 20 covers
- 60 clamps
- 130 bolts

Therefore, the total number of primary assembly items required are:

- 40 rods for the legs
- 40 rods for the top frames
- 13 covers for the tops
- 60 clamps
- 141 bolts

The only answer choice that matches these quantities is D.
