\textbf{185.} The figure below shows the relationship between the current passing through resistors A and B and the potential difference across them. How many times is resistance B compared to resistance A?
\textit{[Figure: $I$-$V$ graph showing two lines through the origin; line B has a steeper slope than line A.]}
\begin{itemize}
\item[(1)] $\dfrac{4}{9}$
\item[(2)] $\dfrac{2}{3}$
\item[(3)] $\dfrac{3}{2}$
\item[(4)] $\dfrac{9}{4}$
