In the following list identify a line which is perpendicular to the line \( 3x - 2y + 11 = 0\).
\(\begin{aligned}[t] x& = 3t, & \\y & = 1 - 2t;\ t\in \mathbb{R} \\ \end{aligned}\)
\(\begin{aligned}[t] x& = 1 + 2t, & \\y & = 2 - 3t;\ t\in \mathbb{R} \\ \end{aligned}\)
\(\begin{aligned}[t] x& = 2 - t, & \\y & = 3 + t;\ t\in \mathbb{R} \\ \end{aligned}\)
\(\begin{aligned}[t] x& = 2 + 3t, & \\y & = 1 + 2t;\ t\in \mathbb{R} \\ \end{aligned}\)
