Statistical Analysis Tool (A) and Toad (C) are not Business Process Management tools. Statistical Analysis Tool is for data analytics, and Toad is primarily a database management tool for Oracle, SQL Server, and other databases. PEGA-PRPC (B) is a well-known BPM platform. Since both A and C are not BPM tools, Option D ('Both a and c') is the correct answer to the question asking which is NOT a BPM tool.
