In most states a person under age 18 does not have

a) testamentary capacity
b) testamentary consent
c) testamentary formality
d) all of these

i think it's d.

To determine the correct answer to this question, let's break down each option and understand their meaning.

a) Testamentary capacity refers to a person's legal ability to create or modify a will. In most states, minors (people under the age of 18) do not have the legal capacity to make a will, as they are considered to lack the necessary maturity and understanding.

b) Testamentary consent refers to the requirement that a person voluntarily and willingly agrees to the terms of their will. Again, minors are generally not considered to have the ability to give informed consent when it comes to creating a will.

c) Testamentary formality refers to the specific legal requirements for creating a valid will, such as having the document properly witnessed and signed. Minors may also not meet these formalities due to their age and legal limitations.

Now that we have a better understanding of each option, let's evaluate the answers:

Option a) implies that minors lack testamentary capacity, which is generally true in most states.
Option b) states that minors lack testamentary consent, which is also generally true in most states.
Option c) suggests that minors may not meet the testamentary formalities, which is also true in most cases.

Therefore, when examining the given options in the context of most states, it becomes clear that the correct answer is d) all of these.
