Christopher is single and no kids, recently learned he has early cancer which has a high degree of survival when caught early. He spoke with his friends about what he should do with his estate and has gathered them in his living room. He discussed that he wished for each of them to point out two personal items of non-financial value that they would want in order to remember him if he should not survive. Christopher then went to his lawyer and the lawyer recommended placing those instructions in:

a. A memorandum of wishes that is referred to in his will.
b. His primary will.
c. A trust executable only upon his death.
d. His secondary will.
