Explanation

LSA++ extends the classic LSA framework by introducing two new layers designed for SAP BW on HANA: the Open Operational Data Store (ODS) Layer (C) enables flexible, virtual access to source data without full transformation, and the BW Workspace Layer (D) empowers business users to self-serviceably model and combine data independently of IT - both concepts not present in classic LSA.

Why A and B are wrong: Corporate Memory (A) and the Architected Data Mart Layer (B) both existed in the original LSA design; they were carried over into LSA++ rather than introduced by it, so they are not exclusive to LSA++.

Memory tip: Think of LSA++ as "LSA for HANA agility" - the two new layers both start with concepts of openness and flexibility (Open ODS = open data access, Workspace = open self-service), which are the hallmarks of what HANA made possible that classic LSA lacked.
