Correct Answer: Oblique

Solution : Given:
1. Oblivion 2. Oblique 3. Oblige 4. Oblate 5. Oblong

Step 1: Compare the first letter of all the words. Since all the words start with the same letter O , then move on to the next letter.
Step 2: The second, and third letters of all the words are the same, i.e., b , and l . So, move on to the next letter.
Step 3: Compare the fourth letter of Obl i vion, Obl i que, Obl i ge, Obl a te, Obl o ng. Oblate will come first as a comes before i , and o according to the alphabetical system. Similarly, (Oblivion, Oblique, Oblige) will come before Oblong as i comes before o according to the alphabetical system.
Step 4: Compare the fifth letter of (Obli v ion, Obli q ue, Obli g e). Oblige will come before Oblivion, and Oblique as g comes before v , and q according to the alphabetical system. Similarly, Oblique will come before Oblivion as q comes before v according to the alphabetical system.
Therefore, the sequence is Oblate, Oblige, Oblique, Oblivion, Oblong.

So, the word Oblique appears in the third position when the given words are arranged in the dictionary order. Hence, the second option is correct.
