You are correct, option A is the sentence that is written correctly. Let me explain how to determine the correct answer.
In this case, we are looking for a sentence that uses proper grammar and punctuation. The correct usage of commas is an important aspect to consider. Commas are used to separate different parts of a sentence, often to set off a dependent clause or to add additional information.
Option A, "When properly designed, an automobile can achieve great fuel efficiency," is correct because it uses a comma to set off the dependent clause "When properly designed." This clause provides additional information about the condition under which an automobile can achieve great fuel efficiency.
Option B, "When properly designed an automobile can achieve great fuel efficiency," lacks the necessary comma. The phrase "When properly designed" should be separated from the rest of the sentence to indicate that it is a dependent clause.
Option C, "When properly designed, great fuel efficiency can be achieved by an automobile," is also correct. In this case, the comma is again used to set off the dependent clause "When properly designed." However, the structure of the sentence is slightly different, with the main focus on "great fuel efficiency" rather than "an automobile."
Option D, "When properly designed great fuel efficiency can be achieved by an automobile," lacks the necessary comma to separate the dependent clause "When properly designed." This makes the sentence grammatically incorrect.
So, your initial choice of option A is correct, but option C is also a valid and correct sentence structure.
