Answer - B.
As per the documentation, when working with write capacity, the rule is to divide the item size by 1KB.Hence, 15.5 divided by 1 is 15.5
When we round-off to the nearest 1KB value, it's 16.Since we are writing 10 items per second, we need to multiply 10*16 = 160.
For more information on Read and Write capacity, please refer to the below link-

To calculate the required provisioned write throughput for best performance, we need to use the following formula:
Required Write Throughput = (Item Size * Write Frequency)/1KB
Where:
- Item Size is the size of each item (15.5KB in this case)
- Write Frequency is the number of items written per second (10 in this case)
- 1KB is the size of a single write operation in DynamoDB.
So, substituting the values:
Required Write Throughput = (15.5 * 10)/1 = 155
Therefore, the correct answer is option C: 155.
