Wires S and T are two copper wires of the same length and are joined in parallel. The diameter of wire S is $3.0\,\text{mm}$. The diameter of wire T is $1.5\,\text{mm}$. A potential difference is applied across the two ends of this parallel combination. What is the value of the ratio $\frac{\text{current in S}}{\text{current in T}}$?
- A$\frac{1}{4}$
- B$\frac{1}{2}$
- C$2$
- D$4$
