Right answer is (c) 6000-14000 potatoes/hour
To explain I would say: The automatic potato planter, which is a potato dropping mechanism contains a hopper and cups. The cup picks up the graded potatoes and carries to furrow opener spout and releases in the furrow. The fertilizer and pesticides can also be placed simultaneously. It can plant 2-4 in rows. Its capacity may be 6000-14000 potatoes/hour.
