Final answer:
The next step after qualifying per clause 4 involves reviewing the results or preparing and submitting a report, depending on the specific scenario.
Step-by-step explanation:
If the procedure was qualified per clause 4, then the next step typically involves review and verification before finalizing the results. Based on the context provided, after a scenario such as an experiment or project has reached a certain stage where preliminary requirements are met (such as qualifying per a specific clause), the logical next steps usually include further validation of the outcomes. This might involve comparing observations with peers, engaging in peer review, making necessary amendments based on feedback, writing summaries and conclusions, and potentially altering the working hypothesis based on the evidence gathered. The context suggests that immediate commencement of work or seeking approval is not the immediate next step following a qualification under a clause, rather, a process of careful review and validation is crucial.
Thus, while the provided information does not directly answer the multiple-choice question, it leads one to infer that the next step after qualification per clause 4 would likely involve reviewing the results (Option B) or potentially preparing and submitting a report (Option C) depending on the specific scenario.
