To connect to a server using TCP/IP, we need to use the Socket class. The constructor of this class takes two parameters - the host name and the port number. So, the correct way to connect to the HTTP port (port number 80) of the server yahoo.com is to use the constructor Socket("yahoo.com", 80). Option A is incorrect as it uses the wrong syntax for the constructor. Option B is also incorrect as it is not a valid method and does not create a socket object. Option D is incorrect as it is a command to run a java program with arguments and does not create a socket object.
