文中哪里体现了an ability to invest in a diversified mix of securities？

问题如下：

Based on the Barksdales’ annuity preferences, which type of annuity should they purchase?

选项：

Deferred fixed

Deferred variable

Immediate variable

解释：

B is correct.

The Barksdales want an annuity with a deferred payout (beginning at retirement) and an ability to invest in a diversified mix of securities. Most deferred variable annuities off?er a diversified menu of potential investment options, whereas a fixed annuity locks the annuitant into a portfolio of bond-like assets at whatever rate of return exists at the time of purchase.
