The "45" in the error message is probably the line number, but that would
be the very end of your file, from what I see.  One possibility is that
there is an invisible control character somewhere in the file, or some
punctuation is unicode instead of ascii.
By any chance did you copy/paste from a work processor?  They often use
different quote and hyphen characters that look similar but are not the
right character.

On Linux or Unix, try this:
    cat -v /etc/dhcpd.conf > /tmp/dhcpd.conf
    diff /etc/dhcpd.conf /tmp/dhcpd.conf
If there are any differences, delete and retype that line (do not
copy/paste).

Or
Open in a plain text editor like Notepad on Windows or gedit on Linux and
then save as a new file, and try the new file.

Or
Open in "vi" or "vim" and look for control characters - should show as "^"
followed by some character, but you won't be able to search for the "^".
