Kasper Bought a Truckload of Gravel from Gita

Kasper bought a truckload of gravel from Gita. The parties agreed that the price would be at least $500. Kasper therefore paid that amount later the same day. He promised to pay the remainder (which the parties estimated to be $200) after Gita weighed the gravel in order to determine its exact price. Gita returned with the truckload of gravel to her supply yard, weighed the gravel, and determined that the total contract price should be $675. Unfortunately, the gravel was stolen before Kasper actually took possession of it. Which of the following statements is TRUE?

A) Although property passed to Kasper when he paid part of the price, the risk remained with Gita until she weighed the gravel.
B) Kasper will bear the burden of the theft if Gita notified him of the total price after the theft occurred.
C) The Sale of Goods Act applies to the facts even thought the subject matter of the contract is gravel, which is a substance that must be taken from land.
D) Risk passed to Kasper because he paid part of the price.
E) Property passed to Kasper as soon as the contract was created because the agreement was concerned with specific goods that were already in a deliverable condition.
