Answer – C
The AWS documentation mentions the following
All LAGs have an attribute that determines the minimum number of connections in the LAG that must be operational for the LAG itself to be operational. By default, new LAGs have this attribute set to 0. You can update your LAG to specify a different value—doing so means that your entire LAG becomes non-operational if the number of operational connections falls below this threshold. This attribute can be used to prevent over-utilization of the remaining connections.
All connections in a LAG operate in Active/Active mode.
