Amy wished to give some jewelry to her friend, Kate, who was on a trip through Asia. She telephoned her best friend, Gina, and asked her to come to Amy's house. When she arrived, Amy told her that she had some jewelry that she wanted to leave to her friend, Kate, but that she had never made a will. Amy asked Gina to take the jewelry and see it was delivered to Kate upon Amy's death. Gina took the jewelry to her own home and kept it for Kate. When Amy died six months later, Gina delivered the jewelry to Kate. Amy was survived by her mother, who is her only heir. Based on the foregoing, if Amy's mother sues Kate to recover the jewelry, who will prevail? Which is the best answer: a. Amy's mother should recover the jewelry because there was no completed gift. b. Amy's mother should not recover the jewelry because there was a completed gift. c. Even if the gift was complete, Amy's mother should recover the jewelry because the gift was causa mortis. d. Amy's mother should not recover the jewelry because Amy's intent was clear
