Juniper Ltd, a Manufacturer of Jams and Jellies, Has Been

Juniper Ltd, a manufacturer of jams and jellies, has been sued by Trevor who alleges that he consumed worms in one of their products and which made him severely ill. Juniper sells all of its products through an independent regional distributor Jellyco. Juniper's manufacturing process entails bottling the jams and jellies when the mixtures are at boiling temperatures and thereafter immediately sealing the containers. It therefore believes that it is impossible that worms could have been in its product when it left the manufacturing plant. Which of the following is its best defence to Trevor's claim?

A) That it did not cause the defect in the product
B) That it does not know how the defect occurred
C) That Jellyco must have caused the defect
D) That Trevor did not really suffer an injury
E) That it owed no duty of care to Trevor
