How many active versions of a flow can you have at a given time?
A . Unlimited
B . 5
C . 1
D . 10

Answer: C

Explanation:

In Salesforce, you can only have one active version of a specific flow at any given time. You can have multiple versions of a flow, but only one can be active. This is because each flow is identified by a unique name, and when a flow is activated, Salesforce deactivates any other versions of the flow with the same name.

The other versions of the flow remain available in Salesforce, but they are not active, and thus are not used when the flow is run. If you need to return to a previous version of the flow, you would need to activate that version, which would automatically deactivate the current active version.
