Which of the following test case design techniques is white box (structure-based)?

Decision testing is a white box (structure-based) test case design technique1. White box (structure-based) test case design techniques are techniques that use the structure or logic of the source code as a test basis to derive test cases and measure test coverage1. Decision testing is a technique that uses decisions (or branches) in the source code as a test basis to measure the coverage achieved by a test suite1. A decision (or branch) is a point in the source code where the control flow can take two or more alternative paths based on a condition1. Decision testing requires every decision (or branch) in the source code to take both true and false outcomes at least once by a test suite1. Therefore, decision testing is a white box (structure-based) test case design technique.
