To find the scale factor of the drawing relative to the statue, we divide the dimensions of the drawing by the corresponding dimensions of the statue. Let's compute:

1. Height: $\text{Scale factor for height} = \frac{6}{36} = \frac{1}{6}$

2. Length: $\text{Scale factor for length} = \frac{5}{30} = \frac{1}{6}$

Since both height and length have the same ratio, the scale factor is: $\frac{1}{6}$

Thus, the correct answer is: $\boxed{\frac{1}{6}}$

Tip: Always reduce fractions to their simplest form when calculating scale factors to avoid errors.
