Mathew made his will,leaving his estate to his only son,Andrew.Two years later,he felt inclined to leave $100,000 toward a new old age home under construction in his locality.Mathew may make this bequest:

A) by executing a codicil.
B) by adding the bequest to the original will and initialing it.
C) by writing the bequest on a separate sheet and affixing it to the original.
D) by executing a durable power of attorney.

A codicil is a legal document that modifies or adds to an existing will. In this case, Mathew can use a codicil to add the bequest of $100,000 to the new old age home under construction. It is important to use a codicil instead of adding it to the original will or affixing it to a separate sheet because this ensures that the bequest is properly executed and does not cause any confusion or disputes after Mathew's death. A durable power of attorney is not applicable in this situation as it deals with appointing someone to make decisions on behalf of the testator, which is not relevant in this scenario.
