Final answer:
Undue influence in the context of wills is typically inferred when a beneficiary has the means or position to exert substantial influence over the testator's decision-making, and this is indeed considered true.
Step-by-step explanation:
Undue influence may indeed be inferred when a named beneficiary is in a position to influence the making of a will. This legal concept occurs when the testator (the person making the will) is heavily influenced by another person who has the power to override the testator's free will, resulting in a will that reflects the influencer's desires rather than the testator's. Situations that suggest the potential for undue influence include a beneficiary who has the ability to bestow a large inheritance on survivors, or a beneficiary who is taking care of someone frail to the point of dependency. Therefore, the correct answer to the question is A. true.
