B 3
Selected Answer: B
Upgrading a Switch Running Incompatible Software
The auto-upgrade and auto-advise features let a switch with software packages that are incompatible with the switch stack be upgraded to a compatible software version so it can join the switch stack.

Selected Answer: B
Answer B looks right.
"If the stack master detects that the software on a new switch does not match, it upgrades (or downgrades) the new switch with the active image that is running on the switch stack by using the automatic upgrade (auto-upgrade) and the automatic advise (auto-advise) features."
