The correct spelling is "PLUTOCRAT," which refers to a person who is part of the ruling class, typically based on wealth.
- "PLOTUCRAT" is incorrect because of the swapped letters in the first syllable.
- "PLUTOCRET" is incorrect as it introduces an extra "T" and changes the meaning of the word.
- "PLUTOCREAT" is also incorrect due to the wrong ending.
Thus, the correct answer is (A).
