The correct sentence is:
A. When properly designed, an automobile can achieve great fuel efficiency.
This sentence uses proper punctuation by placing a comma after the introductory phrase "When properly designed".
To determine which of the sentences listed is written correctly, we need to analyze each option's grammar and punctuation.
A) "When properly designed, an automobile can achieve great fuel efficiency."
This sentence is punctuated correctly. It uses a comma to separate the introductory phrase "when properly designed" from the main clause "an automobile can achieve great fuel efficiency."
B) "When properly designed an automobile can achieve great fuel efficiency."
This sentence is missing a comma after the introductory phrase "when properly designed." The correct punctuation should separate the introductory phrase from the main clause, so Option B is incorrect.
C) "When properly designed, great fuel efficiency can be achieved by an automobile."
This sentence is grammatically correct. It uses a comma after the introductory phrase "when properly designed" and correctly constructs the sentence.
D) "When properly designed great fuel efficiency can be achieved by an automobile."
