Which programming languages can you use for application development on SAP HANA extended application services?

The correct answer indicates that application development on SAP HANA extended application services can utilize Node.js and C++. This is significant because Node.js is a popular JavaScript runtime that is well-suited for building scalable network applications, making it a great fit for modern web environments, especially when paired with HANA's capabilities for high-performance data processing. C++, while not as commonly used for web applications, can also be integrated into HANA for performance-critical tasks or extensions.

This pairing reflects SAP's focus on modern application development practices, enabling developers to leverage the versatility of Node.js while also addressing performance needs with C++. This approach aligns with SAP HANA's architecture designed for high-speed analytics and transactional processing, allowing for efficient and responsive application experiences.

The other options provided do not align with the supported programming environments for SAP HANA extended application services. While languages such as Python, PHP, Java, and Ruby have their strengths, they are not the primary focus for application development in the context of SAP HANA's specific architecture and optimization for high performance.
