Let's analyze the circuit in the image and solve the problem step by step.

### Description of the Circuit
- The circuit shown is a combination of parallel connections involving three switches (S1, S2, S3).
- Each switch controls a set of resistors (lamps) connected in parallel.
- All resistors (lamps) \( L_1, L_2, L_3, L_4, L_5, L_6 \) have the same resistance of \( 3 \, \Omega \).
- The total voltage provided by the battery is \( 3 \, V \).

### Steps to Solve:
1. **Identify Active Paths:**
   - The problem specifies that **Switch 3 is open (off)**. Therefore, the path containing \( L_4, L_5, L_6 \) is not part of the circuit.
   - Only the resistors connected through Switch 1 and Switch 2 are in the circuit, which are \( L_1, L_2 \) (through Switch 1) and \( L_3 \) (through Switch 2).

2. **Calculate Equivalent Resistance:**
   - Since \( L_1 \) and \( L_2 \) are in parallel:
     \[
     \frac{1}{R_{12}} = \frac{1}{R_{L_1}} + \frac{1}{R_{L_2}} = \frac{1}{3} + \frac{1}{3} = \frac{2}{3}
     \]
     \[
     R_{12} = \frac{3}{2} \, \Omega = 1.5 \, \Omega
     \]
   - \( L_3 \) is connected separately (also \( 3 \, \Omega \)).

   Since \( R_{12} \) and \( L_3 \) are in parallel:
   \[
   \frac{1}{R_{\text{total}}} = \frac{1}{R_{12}} + \frac{1}{R_{L_3}} = \frac{1}{1.5} + \frac{1}{3} = \frac{2}{3} + \frac{1}{3} = 1
   \]
   \[
   R_{\text{total}} = 1 \, \Omega
   \]

3. **Calculate Total Current:**
   - Using Ohm's Law:
     \[
     I_{\text{total}} = \frac{V_{\text{total}}}{R_{\text{total}}} = \frac{3 \, V}{1 \, \Omega} = 3 \, A
     \]

### Conclusion:
The total current flowing out of the battery is **3.0 A**. However, this result does not match any of the provided options, which suggests an interpretation issue. Let's check the standard options:

Given the current calculation, it should match one of the options. A closer look:

- The total resistance could be misinterpreted in other contexts, but the exact calculations lead to the final current.

However, to confirm which answer fits, it could require an interpretation of 'simplified' resistance during an educational test.

Do you want me to refine this further, or would you like more details on each step?
