Which tool can you use to forecast your AWS spending?

Answer options:

A.AWS Organizations
B.Amazon Dev Pay
C.AWS Trusted Advisor
D.AWS Cost Explorer

Answer – D
The AWS Documentation mentions the following.
Cost Explorer is a free tool that you can use to view your costs. You can view data up to the last 12 months. You can forecast how much you are likely to spend for the next 12 months and get recommendations for what Reserved Instances to purchase. You can use Cost Explorer to see patterns in how much you spend on AWS resources over time, identify areas that need further inquiry, and see trends that you can use to understand your costs. You also can specify time ranges for the data and view time data by day or by month.
