If you add a battery to a series circuit, what will happen to the current in the circuit?

A. The current both stayed the same since there is the same resistance
B. The comment will increase since there is less resistance
C. The current will increase since there is more voltage
D. The current will decrease since there is more potent

I put C because if you have more voltage it will make everything brighter it will increase the current . Is this correct?
Thank you

c is correct IF YOU CONNECT THE BATTERY CORRECTLY, but if you connect it backwards, it reduces voltage
Thank you
