The correct answer is D. admitted.

To admit something is to say that it is true. In this case, the thief admitted that he had stolen the watch.

The other options are incorrect because they do not mean the same thing as admit.

  • Conceal means to hide something. The thief did not hide the fact that he had stolen the watch, he admitted it.
  • Disprove means to prove that something is not true. The thief did not disprove the fact that he had stolen the watch, he admitted it.
  • Deny means to say that something is not true. The thief did not deny that he had stolen the watch, he admitted it.
