An electric circuit is set up in such a way that the positive terminal of a battery V is connected to a bulb `B_(1)` which is connected to a resistor R which is connected to bulb `B_(2)`. `B_(2)` is finally connected to the negative terminal of the battery. both the bulbs are blowing. if the value of K is increased, then

A

`B_(2)` will become dimmer but brightness of `B_(1)` will remain unchanged

B

Both `B_(1) and B_(2)` will remain unchanged

C

Both `B_(1) and B_(2)` will become dimmer
