✅ A. Vehicle is moving at a speed of 100 km/h. This car is red ❌ B. Car is moving at a speed of 100 km/h. This car is red ❌ C. This car is red ❌ D. Compilation error ❌ E. Runtime error ❌ F. None of the above
Explanation: The code defines two classes Vehicle and Car. Vehicle is a superclass that has a protected instance variable speed and a method move() that prints the current speed of the vehicle. Car is a subclass of Vehicle that adds a private instance variable color and a method display() that prints the color of the car. The Main class creates a Car object myCar with a speed of 100 and a color of "red". The move() method is called on myCar, which is inherited from Vehicle, and it prints "Vehicle is moving at a speed of 100 km/h". The display() method is then called on myCar and it prints "This car is red". Therefore, the correct answer is option A Vehicle is moving at a speed of 100 km/h and This car is red. The output first shows the message printed by the move() method of the Vehicle superclass, and then the message printed by the display() method of the Car subclass.

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
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.”
