❌ A. Color: ✅ B. Color:null ❌ C. Color:White ❌ D. Compiler error on line 4. ❌ E. Compiler error on line 10. ❌ F. Compiler error on line 11.
Explanation: Line 10 calls the constructor on lines 3–5. That constructor calls the other constructor. However, the constructor on lines 6–8 assigns the method parameter to itself, which leaves the color instance variable on line 2 set to its default value of null

Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
