It occurs when changes in two branches overlap and cannot be merged automatically.

It indicates identical changes in all branches.

It alerts the user that commits have been pushed incorrectly.

It means there is an error in the code.

The command git clone is used to:

Copy an existing repository to the local machine.

Initialize a new Git repository.
