Answer - B.
The AWS Documentation mentions the following.
Amazon DynamoDB global tables provide a fully managed solution for deploying a multi-region, multi-master database without building and maintaining your own replication solution.
When you create a global table, you specify the AWS regions where you want the table to be available.
DynamoDB performs all of the necessary tasks to create identical tables in these regions and propagate ongoing data changes to all of them.
Option A is incorrect because there is no such option of Multi-AZ.
And this is enabled by default as data is replicated across at least 2 AZs.
Option C is incorrect because there is no such feature.
Option D is incorrect because increasing read and write capacities does not help to reduce latency in different regions.
