Answer: Rn :)))) no explanation needed
There is no image??? i think you forgot it attach it
If the resistor is in series with the rest of the circuit then a is the correct answer. The voltage across the resistor in series with another resistor is
![V \frac{R}{R+r}](https://tex.z-dn.net/?f=V%20%5Cfrac%7BR%7D%7BR%2Br%7D%20)
where R is the big resistor and r is the small one and V is the total voltage drop across both. This is called a voltage divider
