B. Equivalence class partitioning
C. Boundary value testing AND Equivalence class partitioning
D. Decision tables
✅ The correct answer is option B.
Explanation: Boundary value analysis is a software testing technique in which tests are designed to include representatives of boundary values.

by
A. An application-composition model
B. A post-architecture model
C. A reuse model
D. An early design model
✅ The correct answer is option D.
Explanation: Estimates are based on function points, which are then converted to number of lines of source code. The formula follows the standard form discussed above with a simplified set of seven multipliers.
