Solution

The correct option is C $I_{A} = 2 A, I_{B} = 1 A$
In a parallely connected circuit, the potential difference is same across each resistor. The potential difference given in the question is 2 V. So, the current across each resistance is calculated from the formula I=V/R.
The current flowing across resistor A is $I = \frac{V}{R} = \frac{2}{1} = 2 A$ .
The current flowing across resistor B is $I = \frac{V}{R} = \frac{2}{2} = 1 A$ .
Hence, the value of current across A and B are 2 A and 1 A respectively.
