Best answer

Correct choice is (d) 25mm

Explanation: Seed tube is which carries the seeds from the metering device to the boot. Seed tubes are provided at the lower end of the feed cups. They conduct seeds from feed cups to the furrow lines through suitable boots and furrow openers. Polythene or rubber tubes are also used for this purpose. The minimum diameter of seed and fertilizer tube is 25 mm.
