Two nichrome wires \( A \) and \( B \), each of length \( 5 \mathrm{~cm} \) and of radius \( 2 \mathrm{~cm} \) and \( 6 \mathrm{~cm} \) respectively are connected to each other in series. If a current of 5 A flows through the combination of wires, the ratio of potential difference across wire \( A \) to that across wire \( B \) will be:
a. \( 6: 1 \)
b. \( 1: 6 \)
c. \( 9: 1 \)
d. \( 1: 9 \)
