chatgpt: Option D: with tracer.start_span('dnac-api-calls') as span: This line of code starts a new span for tracing API call operations. It uses Python’s with statement to ensure that the span is properly closed after the operations within the span are completed. Option E: tracer = init_tracer('dnac-tracer3') This line initializes a new tracer object with the name 'dnac-tracer3', which is used to track the API calls.

dnac-tracer3 = init_tracer('dnac-tracer3') with dnac-tracer3.start_span('dnac-api-calls') as span: and tracer = init_tracer('dnac-tracer3') with tracer.start_span('dnac-api-calls') as span: looks the same but at picture we can see SPAN name - dnac-tracer3 so correct A and C with dnac-tracer3.start_span('dnac-api-calls') as span: dnac-tracer3 = init_tracer('dnac-tracer3')
