• B. Fitness experts, have coined, the phrase sitting is the new smoking in an effort to raise awareness about the negative health effects of sitting at a desk all day every day.
• C. Fitness experts have coined the phrase sitting is the new smoking, in an effort to raise awareness about the negative health effects of sitting at a desk all day every day.
• D. Fitness experts have coined the phrase sitting is the new smoking in an effort to raise awareness about the negative health effects of sitting, at a desk all day every day.

Answer: (A)

The main idea here is how to attach a purpose phrase to a sentence without interrupting the flow. The clause “in an effort to raise awareness about the negative health effects of sitting at a desk all day every day” explains why they coined the phrase and should stay directly connected to the main clause.

Keep the sentence as one smooth unit: “Fitness experts have coined the phrase sitting is the new smoking” and then add the purpose phrase without a comma. That preserves the direct object “the phrase sitting is the new smoking” and treats the purpose phrase as part of the intended meaning, not as a separate, offset element.

The other options pull the sentence apart in ways that disrupt reading: inserting commas around the verb phrase breaks the subject–verb connection; placing a comma inside the object or before the final prepositional phrase splits the meaning of the noun phrase or creates an unnecessary pause.
