Answer: D. It takes precedence over a prior conflicting will
Step-by-step explanation:
"Causa mortis" is a Latin word that represent,"because of death". A gift causa mortis is defined as a gift created in the anticipation of the death to come. The example is a donor gift made on his or her death bed. However, the donor may not necessarily have to be dead for the donation to be deemed a causa mortis.
According to the law, gift causa mortis predominates over a historical dispute on will.
Hence, the correct option is D. It takes precedence over a prior conflicting will.
