Answer:
A) joint and survivor
Step-by-step explanation:
A joint and survivor annuity is generally taken by married couples, and the payments continue as long as one spouse is alive. In this case, the annuity payment while both spouses were alive was $250, but it reduced to half when the wife died. Payments cease only after both spouses die.
On the other hand, a joint annuity will make payments only while both spouses are alive, and the payments will cease when one of the two, or both of the spouses die.
