Correct Answer: iv, i, iii, ii

Solution : Given:
i. Latitude ii. Longitude iii. Laugh iv. Latent

Step 1: Since all the words start with the same letter L , so move on to the next letter. The second letter of each word is – a , o , a , a . Longitude will come after other words in the sequence as o comes after a in the alphabetical system.
Step 2: The third letter of (Latitude, Laugh, Latent) is – t , u , t . Laugh will come after other words in the sequence as u comes after t in the alphabetical system.
Step 3: Compare the fourth letter of (Latitude and Latent). Latent will come before Latitude in the sequence as e comes before i in the alphabetical system.

So, the sequence is Latent, Latitude, Laugh, Longitude, that is→iv, i, iii, ii
Hence, the third option is correct.
