Explanation

Citrix leading practices mandate a minimum of 2 Delivery Controllers for any production deployment, regardless of user count - the second controller provides high availability so that if one fails, sessions can still be brokered without downtime. Option A (1 controller) is technically functional but violates Citrix's own leading practices, which treat single-controller deployments as a single point of failure. Options C (3) and D (4) are valid for larger or more resilient deployments but exceed the minimum requirement the question asks for - don't confuse "recommended for scale" with "minimum required."

Memory tip: Think "2 = minimum, no matter how small" - Citrix treats HA as non-negotiable even at 1 user, so the floor is always 2 controllers in a leading-practices context.
