Anna Liza is planning to retire this year. Her firm has offered her $2$

options, a lump$-$sum retirement payment of RM $400,000$ and second

a RM$50,000$ lifetime at the end of each year. Anna Liza is in

reasonably good health and expects to live for at least $20$ more years.

Which option should she choose, assuming that a $9$ percent annual

interest rate is appropriate to evaluate the annuity?
