Explanation:
Transitions are single words, phrases or sentences that establish a logical connection between sentences and paragraphs. They develop a sense of what is to come later in the content. Transitions maintain a logical flow of ideas and provoke the reader to think and keep reading for new and interesting information.
In the current example, B is the appropriate transition as it conveys to the reader that something substantial is about to happen without mentioning the actual event.
