In software development, which of the following is an appropriate explanation of a test that uses stubs?

During the execution of a program, the contents of a variable or register are displayed as required, and the test is continued after the contents are modified if necessary.

Each time a specific instruction is executed, the contents of registers and main memory are dumped to check whether the process is executed correctly.

When a top-down test is performed, a dummy lower-level module that is called by the upper-level module is prepared to stand in for an unfinished portion of the program.

When a unit test for a module is performed, a dummy higher-level module that calls the module is prepared to check whether the operation is executed correctly.

Test data about the part of a program shown in the flowchart below is specified by decision condition coverage (branch coverage). When this test data is changed to being specified by multiple-condition coverage, which of the following is the appropriate test data to be added? Here, the part enclosed by parentheses () represents the set of test data.

The flow of code:

P1;

if (A > 6 or B = 0) then P2;

Current test data:

Test data by decision condition coverage (branch coverage)

(A = 4, B = 1), (A = 5, B = 0)

(A = 3, B = 0), (A = 7, B = 2)

(A = 3, B = 2), (A = 8, B = 0)

(A = 4, B = 0), (A = 8, B = 0)

(A = 7, B = 0), (A = 8, B = 2)
