**Problem Statement:**

Reparametrize the curve with respect to arc length measured from the point where \( t = 0 \) in the direction of increasing \( t \).

**Given Function:**

\[ \mathbf{r}(t) = (-2 + 3t)\mathbf{i} + (-1 - 2t)\mathbf{j} + 4\mathbf{k} \]

**Options:**

a. \[ \mathbf{r}(s) = \left\langle -2 + \frac{3s}{\sqrt{13}}, -1 - \frac{2s}{\sqrt{13}}, 0 \right\rangle \]

b. \[ \mathbf{r}(s) = \left\langle -\frac{3s}{\sqrt{13}}, -\frac{2s}{\sqrt{13}}, 0 \right\rangle \]

c. \[ \mathbf{r}(s) = \left\langle -2 + \frac{3s}{\sqrt{13}}, -1 - \frac{2s}{\sqrt{13}}, 4 \right\rangle \]

d. \[ \mathbf{r}(s) = \left\langle -2 + \frac{s}{\sqrt{13}}, -1 - \frac{s}{\sqrt{13}}, 4 \right\rangle \]

e. \[ \mathbf{r}(s) = \langle -2 + \sqrt{13}s, -1 - \sqrt{13}s, 4 \rangle \]
