Correct Answer: C
Choice C is the best answer. This question tests comma usage with nonessential (nonrestrictive) phrases.
- Context clues: The phrase provides extra information but isn't essential to identify the technology.
- Meaning: Nonessential phrases are set off by commas on both sides.
- Verify: "The new technology, developed by a team of engineers in Silicon Valley, promises to revolutionize..." correctly brackets the phrase.
💡 Strategy: Set off nonessential phrases with commas on both sides when they appear mid-sentence.
Choice A is incorrect because it lacks both necessary commas. Choice B is incorrect because it lacks the closing comma. Choice D is incorrect because it lacks the opening comma.
