In the context of alphabetizing words, the proper order is determined by the sequence of letters from the beginning of each word. The first step is to compare the first letters of each word.

Here, the words can be analyzed as follows:

- "polarize" starts with 'p'

- "omnipotent" starts with 'o'

- "polygraph" starts with 'p'

- "omniscient" starts with 'o'

Since 'o' comes before 'p' in the alphabet, both "omnipotent" and "omniscient" will come before "polarize" and "polygraph." Among the words starting with 'o', "omnipotent" comes first because the next letter in "omnipotent" is 'm,' which precedes 'n,' the next letter in "omniscient." Therefore, "omniscient" is second in alphabetical order after "omnipotent."

So, when arranged correctly in alphabetical order, the sequence starts with "omnipotent," followed by "omniscient," followed by "polarize," and lastly "polygraph."
