ALoad balancer, static routing, manual rollback process

BManual deployment script, user feedback form, database backup

CContinuous integration server, code linter, version control

DTraffic router, monitoring system, automated rollback controller

Step-by-Step Solution

Solution:

A traffic router directs user requests between old and new versions; monitoring system tracks error rates.
Step 2: Include automated rollback for quick response
An automated rollback controller triggers rollback if error thresholds are exceeded.
Final Answer:
Traffic router, monitoring system, automated rollback controller -> Option D
Quick Check:
Canary needs routing + monitoring + rollback [OK]

Quick Trick: Combine routing, monitoring, and rollback for safe canary [OK]

Common Mistakes:

Ignoring automation in rollback
Confusing deployment tools with monitoring
Missing traffic routing component
