Peter, a disgruntled ex-employee of Zapmaky Solutions Ltd., is trying to jeopardize the company's website http://zapmaky.com. He conducted the port scan of the website by using the Nmap tool to extract the information about open ports and their corresponding services. While performing the scan, he recognized that some of his requests are being blocked by the firewall deployed by the IT personnel of Zapmaky and he wants to bypass the same. For evading the firewall, he wanted to employ the stealth scanning technique which is an incomplete TCP three-way handshake method that can effectively bypass the firewall rules and logging mechanisms.
Which if the following Nmap commands should Peter execute to perform stealth scanning?
