When buyer pays some part of the price of goods to the seller, the seller is called

unpaid seller
partly paid-up seller
short paid seller
None of these

The correct answer is: A. unpaid seller.

A partly paid-up seller is a seller who has received some payment for the goods but not the full amount. A short paid seller is a seller who has received the full amount for the goods but has not delivered them.

An unpaid seller is a seller who has not received any payment for the goods. This can happen if the buyer has not paid the full amount or if the buyer has not paid at all. An unpaid seller has certain rights, such as the right to stop delivery of the goods and the right to sue the buyer for the price of the goods.

I hope this helps!
