Answer is D. Looking for Cost Effective option... Go with Aurora serverless with pause option. Pause after inactivity – The amount of time with no database traffic to scale to zero processing capacity. When database traffic resumes, Aurora automatically resumes processing capacity and scales to handle the traffic.
