Option **A**

#### Explanation:

In diagram 1.

Given

Using Ohm's Law we get the resistance

#R=V/I#

#=>R=3.0/0.5=6Omega#

In diagram 2.

The voltage remains same and there is no change in the position of voltmeter. As such

An identical resistor is added in parallel with the first resistor. The combined resistance

#1/R_"total"=1/R_1+1/R_2#

#=>1/R_c=1/6+1/6#

#=>1/R_c=1/3#

#=>R_c=3Omega#

New current is found using Ohm's Law

#I=V/R#

#=>I=3.0/3#

#=>I=1A#
