Explanation:
Option C is the correct answer. It is the option that correctly uses ellipsis to show that part of the quote has been left out.
Looking at the above option, one will discover that even though a part of the quote was left out, the adding of ellipsis still made the quote to convey a full meaning. Unlike the other options e.g. Options A and D that didn't really show if a part of the quote was left out. Option B didn't give a coherent meaning.
