A and B are brothers. B is 95 years old and his wife C, age 97, is in a full-time care home. B's will currently leave everything to his wife, C. However, A has advised B he should update the will and name A as the beneficiary instead, so A can then use the assets to take care of C after B' death. A explained to B that with the proper financial resources, he would be in a good position to take care of C, as she cannot manage her own finances. B has agreed with A, as he seems to think that this makes sense given his estate planning objectives. What should A be aware of in this scenario?

a. Naming Aas enduring power of attorney for property would be a more effective way of reducing risk while allowing Jim's control over B's finances to endure after his death b. Rather than making A the beneficiary. B should consider adding A as the co-testator of the will as a more suitable option to meeting his estate planning objectives c. B cannot unilaterally make changes to his will after age 90 without a medical assessment from a provincial health authority certifying that he has the required mental capacity d. In order to demonstrate testamentary capacity B must understand the potential claims from C as someone who would normally expect to be a beneficiary under his will
