A father is writing his will (the testator) and is naming as beneficiaries his 2 adult sons - Son A and Son B. Each one will get an equal share of the father's estate "per capita" upon the father's death. Each of the sons has children (the grandchildren of the testator) who are not yet adults. Son A has 2 young children - Grandchild A1 and Grandchild A2 and Son B has 2 children, Grandchild B1 and Grandchild B2. If Son A predeceases the testator, then:
A. Son A's 1/2 share goes into his estate
B. Son A's share goes to Son B
C. Grandchild A1 gets 25% and Grandchild A2 gets 25% of the estate's assets upon the death of the testator
D. the deceased son's share reverts back to the father's estate
