11) C

The resistors are in series.

1 – Wrong
Voltage is different in each component of the circuit.

2 – Correct
Resistance of R₁ is twice that of R₂.
Since V ∝ R, voltage in R₁ will also be twice that of R₂.

3 – Wrong
Voltage of R₂ is half of R₁

4 – Correct
The current across all components in a series circuit will be the same.

5 – Wrong
Current is the same in both resistors.

6 – Wrong
Current is the same in both resistors.

Since statements 2 and 4 are correct, C is the answer.
