ANSWER is a pause in the CREATIVE process. Writer's block actually means 'a condition, primarily associated with writing, in which an author is unable to PRODUCE new work or experiences a creative slowdown.'In the passage, it means a temporary stoppage or a pause in the creative writing process.In the second paragraph, we can see in the LINES- "However, in the process of creative writing ONE can sometimes experience writer's block: this is just a temporary lull in the creative process."Lull means- a short period of quiet between times of activity (गतिविधि के विभिन्न चरणों में संक्षिप्त विराम की सि्थति; शांति, मंदी)Hence, the correct answer is option 2.
