• A.You can use the Declarative Directive Generator to help structure statements for Declarative Pipelines and use the Snippet Generator to help structure statements for Scripted Pipelines.

• C.Scripted Pipelines can implement some functionality that Declarative Pipeline syntax does not support, although small bits of scripted syntax can be included In a Declarative Pipeline by using the "script" step.
• D.Scripted Pipelines require extensive knowledge of the Apache Groovy syntax wher ease Declarative Pipelines can be implemented with minimal understanding of Groovy and so have a lower risk of syntax errors than Scripted Pipelines.
