If it is possible to make only one meaningful word with the third, sixth and eighth letters of the word ORDINATE, then the third letter of the word formed is the answer. If no meaningful word is formed, then give $\mathrm{`X}´$as the answer. If more than one such words can be formed, then give $\mathrm{`Z}´$as the answer. And if one meaning full word can be formed, then give $D$ as the answer.
