Final answer:
The most responsible and efficient payment option for Devon's monthly rent is to use online auto bill pay, which eliminates the need for manual intervention and ensures on-time payment (Option D).
Step-by-step explanation:
When Devon is looking for the most responsible and efficient way to ensure that rent is paid on time, the best option among those listed would be to use online auto bill pay.
This method is highly efficient because it automates the payment process, eliminating the need for reminders or the risk of postal delays.
Additionally, it saves time, as Devon would not need to hand-deliver cash or write and mail a check each month.
With auto bill pay, the payment is electronically transferred from Devon's bank account to the landlord's account on a scheduled date each month.
Hand-delivering cash may seem instantaneous, but it requires Devon to physically go to the landlord's location, which takes time.
Setting up a text alert to remind him to write and mail a check is not the most efficient, as it relies on Devon's ability to follow through each month and also depends on the postal service for on-time delivery.
Asking his employer to set up a direct deposit specifically for rent is unlikely to be an option most employers would agree to, as it involves the employer in personal financial transactions.
Hence, the correct answer is Option D.
