When multiple parametrize decorators are applied, pytest creates the Cartesian product of all parameter sets.
Step 2: Analyze options
Because pytest generates all possible combinations of the parameters from each decorator. correctly states that all combinations are generated, multiplying test cases. Because pytest runs each decorator sequentially, adding tests linearly. incorrectly suggests linear addition. Because only the first decorator is considered and others are ignored. is false; all decorators are considered. Because pytest merges parameter lists into a single list without combinations. is incorrect as pytest does not merge lists without combinations.
Final Answer:
Because pytest generates all possible combinations of the parameters from each decorator. -> Option B
