Hello candidate,

With due concern, I would like to mention that the questions you have asked seems to be incomplete or is lacking some necessary information which should be mentioned.

As the question says, that a voltage of 9 volts is produced using a resistor of 10 kilo ohm in power, but it is not convenient other information regarding the options you have mentioned to get out the final answer.

Kindly recheck the question!!

Have a good day.
