Two resistors \( A \) and \( B \) have resistances \( R_{A} \) and \( R_{B} \) respectively with \( R_{A}R_{B} \). The resistivities of their materials are \( \rho_{A} \) and \( \rho_{B} \).
(a) \( \rho_{A}\rho_{B} \)
(b) \( \rho_{A}=\rho_{B} \)
(c) \( \rho_{A}\rho_{B} \)
(d) The information is not sufficient to find the relation between \( \rho_{A} \) and \( \rho_{B} \).
