Statement $I :$ If the number of turns in the coil of a moving coil galvanometer is doubled then the current sensitivity becomes double.
Statement $II :$ Increasing current sensitivity of a moving coil galvanometer by only increasing the number of turns in the coil will also increase its voltage sensitivity in the same ratio:
In the light of the above statement, choose the correct answer from the options given below :
