What does a voltmeter do in an electric circuit?

Correct answer: D. measures potential difference and is connected in parallel
A voltmeter measures potential difference and is connected in parallel.
Answer: measures potential difference and is connected in parallel.
Why not the others: measures current and is connected in series: that is what a ammeter does. melts to break a circuit when the current is too high: that is what a fuse does. opens or closes a circuit: that is what a switch does.
