Explanation:

Correct Option: D. Efficient processing of large volumes of transactions at once

Batch processing is particularly advantageous in scenarios like processing millions of daily transactions for a financial services company due to its ability to handle large datasets efficiently. The key benefits include:

High-throughput: It can process vast amounts of data in bulk, making it ideal for large-scale operations.
Cost-effectiveness: By processing data in batches, it leverages economies of scale, reducing the cost per transaction.
Scalability: The batch processing system can easily scale to accommodate increasing volumes of transactions without a significant overhaul of the infrastructure.

Why other options are not correct:

A. Simplified data integration across various financial platforms: While batch processing can integrate data from multiple sources, its primary advantage is not simplifying integration but rather handling large volumes of data efficiently.
B. Real-time fraud detection capabilities: Batch processing is not suited for real-time applications like immediate fraud detection due to its inherent processing delays.
C. Immediate processing of transactions with low latency: The nature of batch processing involves processing data in intervals, which introduces latency, making it unsuitable for applications requiring immediate processing.
