Explanation
Removing all jewelry (rings, bracelets, watches) is the very first step because it eliminates the risk of physical injury and electrical hazards before anything else is done. Jewelry can snag on sharp internal components, bridge contacts and cause shorts, or get caught in fans. ESD precautions (B and C) are important too, but they protect the components from damage - removing jewelry first protects the technician. Disconnecting power (D) is also necessary but comes after removing jewelry as part of the safety sequence. Safety of the person always precedes component protection.
