Correct Answer: e, a, c, b, d

Solution : Given:
a. Collect b. Collinear c.Collection d. Column e. Collapse

Step 1: Compare the first, second, and third letter of each word. Since all the words start with the same letter C , o , and l , then move on to the next letter.
Step 2: The fourth letter of each word is either l or u . Based on the alphabetical order of these letters, we can arrange them – Col l ect, Col l inear, Col l ection, Col l apse, Col u mn.
Step 3: Compare the fifth letter of (Coll e ct, Coll i near, Coll e ction, Coll a pse). Collapse will come before Collect, Collinear, and Collection as a comes before i and e in the alphabetical system. Similarly, Coll e ct and Coll e ction will come before Coll i near as e comes before i in the alphabetical system.
Step 4: Compare the eighth letter of (Collect, Collect i on). Collect will come before Collection as Collect is an 8-letter word.

So, the sequence is Collapse, Collect, Collection, Collinear, Column, or e, a, c, b, d. Hence, the first option is correct.
