Let's begin by explaining key terminologies used:
A single-payment fixed annuity refers to a contract in which the client pays a lump sum of money to the insurance firm. In return, the insurance firm pays the client a certain amount periodically over a set period of time & at a specified interest rate or APR
For options A & D, the client makes yearly payment to the insurance firm (this is contrary to the lump sum that should originally be paid). Option D does not indicate a specified interest rate, it only gave an estimate of "minimum APR of 3.4%"
Option B has a specified APR of 3.4% & the client pays a lump sum upfront
Hence, option B is the correct answer
