问题如下：
Marion concerns about longevity risk given their family generally have long life spans. Both Marion and his wife shelly want an annuity begins later in life (not begin until age 85) that will provide additional security and can supplement income in later years. Which type of annuity best suits the Marion’s goal for supplemental income in their later years?
选项：
A.Advanced life deferred
B.Deferred variable
C.Deferred fixed
解释：
A is correct.
考点: Annuity
解析:与immediate payout annuity不同的是，Advanced life deferred (ALDA’s)的支付开始于人生较晚阶段，例如，当个人年满80岁或85岁时。与成本相比，ALDA将提供最大的收入补充水平，因为付款是在遥远的未来进行的，当付款开始时，预期寿命较短，有可能一些投保人在付款尚未开始前就已经离世。
老师你好，我看了助教在另一个同学的提问中给出的答案，如下：
“嗨，从没放弃的小努力你好：
Annuity分为life annuity 和Deferred fixed annuity 以及Deferred variable annuity， life annuity 是给到死的，而Deferred fixed annuity 以及Deferred variable annuity都是指给一段时间。这个人想要的年金是 provide additional security and can supplement income in later years.可见他是想要一个能够给到死的年金，所以不选C”
请问这个解答是不是有误？life annuity 和Deferred fixed annuity 以及Deferred variable annuity不是都是给到死的吗？
