Answer
Correct Answer: No correction required
Explanation
Given data
- Structure: “one of the most + plural noun + of + singular time-period”.
Concept/ApproachAfter “one of the most…”, the head noun must be plural (inventions). The prepositional phrase “of this century” is correct because century refers to a single time period.
Option analysisNo correction required — original uses the standard pattern “one of the most important inventions of this century.” ✅invention of this century — singular noun after “one of the most” is incorrect.invention of these century — wrong demonstrative and number mismatch.invention of centuries / of the centuries — illogical scope and wrong number.
Final AnswerNo correction required
