What are the failover types supported under the synchronous-commit availability mode Always On availability Groups )? Select all that apply?

What does it mean to be in synchronous commit Availability mode?
Synchronous-Commit Availability Mode. Under synchronous-commit availability mode (synchronous-commit mode), after being joined to an availability group, a secondary database catches up to the corresponding primary database and enters the SYNCHRONIZED state.
How does synchronization occur between two availability replicas?
The synchronization and failover behavior between two availability replicas depends on the availability mode of both replicas. For example, for synchronous commit to occur, both the current primary replica and the secondary replica in question must be configured for synchronous commit.
How to change the Availability mode of a replica?
This topic describes how to change the availability mode of an availability replica in an Always On availability group in SQL Server by using SQL Server Management Studio, Transact-SQL, or PowerShell. The availability mode is a replica property that controls the whether the replica commits asynchronously or synchronously.
What is synchronous commit mode in Windows 10?
Synchronous-commit mode emphasizes high availability over performance and, once the secondary replica is synchronized, supports manual failover and, optionally, automatic failover. You must be connected to the server instance that hosts the primary replica.
