❌ A. Orca diving ✅ B. The code will not compile because of line 2 ❌ C. The code will not compile because of line 8 ❌ D. The code will not compile because of line 9 ❌ E. The output cannot be determined from the code provided
Explanation: This may look like a complex question, but it is actually quite easy. Line 2 contains an invalid definition of an abstract method. Abstract methods cannot contain a body, so the code will not compile and option B is the correct answer. If the body {} was removed from line 2, the code would still not compile, although it would be line 8 that would throw the compilation error. Since dive() in Whale is abstract and Orca extends Whale, then it must implement an overridden version of dive(). The method on line 9 is an overloaded version of dive(), not an overridden version, so Orca is an invalid subclass and will not compile.

Telegram Gives Up On Crypto Blockchain Project
Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. 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.”
