Explanation

A Denial of Service (DoS) attack originates from a single source - in this case, one IP address (10.10.3.23) is flooding the target server (10.10.2.4) with connection attempts, overwhelming it. A DDoS (Distributed Denial of Service) attack (choice B) requires multiple attacking sources simultaneously, which is not the case here. An Xmas attack (choice A) is a specific port scan technique that sets unusual TCP flag combinations to probe a target - it is not a flooding/availability attack. XSS (Cross-Site Scripting) (choice D) is a web application injection attack targeting browsers, completely unrelated to network flooding. The single-source overload pattern clearly identifies this as DoS.
