Google Meet is available in Google Classroom, making it easier and more secure for teachers and students to come together. What are some of the features available?

Option A is correct because Google Meet integrated with Classroom enhances security by preventing students from entering a meeting unsupervised. They are placed in a waiting room until a teacher joins, ensuring appropriate supervision from the start. Option C is also correct because this feature prevents unauthorized individuals from joining the class meeting. Anyone not on the class roster must request to join, giving the teacher control over who participates and maintaining a secure learning environment. Option B is incorrect because it contradicts the security features of Google Meet in Classroom; students cannot enter the meeting at any time without a teacher present, nor can they bypass the "ask to join" feature if they are not on the roster.
