Which command sends the word count of the file infile to the newfile.

Answer: Option A

In Unix, the wc command is used to count words, lines, and characters in a file. The > symbol is used for output redirection, which means that the output of the command preceding it will be written to the specified file.
So, wc infile > newfile is the correct command to send the word count of the file infile to the newfile.
