Final answer:
Making an additional premium payment on Jennifer's Adjustable Life policy does not affect the premium flexibility.
Step-by-step explanation:
When Jennifer made an additional premium payment on her Adjustable Life policy, it would not affect the premium flexibility of her policy. Premium flexibility refers to the ability to change the premium amount or payment frequency. Since Jennifer made an additional payment, this indicates that she is making an extra payment on top of the regular premium, which does not impact the flexibility of the premium.
