What is the visual difference between a regular merge and an octopus merge in Git history?

Which command performs an octopus merge in Git?

A git rebase branch1 branch2

B git merge --squash branch1

C git merge branch1 branch2 branch3

D git cherry-pick branch1

The command 'git merge branch1 branch2 branch3' merges multiple branches at once, which is an octopus merge.

What happens if there are conflicts during an octopus merge?

A Git stops and asks you to resolve conflicts manually

Why use an octopus merge?

A To merge one branch into another

A More than two

B Two

C One

D Zero

An octopus merge commit has more than two parents because it merges multiple branches.

Which situation is NOT suitable for octopus merge?

A Merging multiple feature branches without conflicts

B Merging branches with conflicts

C Merging many small fixes at once

D Combining branches for a release
