To determine the height of the scale model, we need to use the given scale: 2 inches represents 30 feet. We can set up a proportion based on this scale to find the height of the model in inches.

Let $x$ represent the height of the scale model in inches.

$\frac{2 \, \text{inches}}{30 \, \text{feet}} = \frac{x \, \text{inches}}{180 \, \text{feet}}$

Now, cross-multiply to solve for $x$:

$2 \times 180 = 30 \times x$

$360 = 30x$

Now, divide both sides by 30:

$x = \frac{360}{30} = 12 \, \text{inches}$

Thus, the height of the scale model is 12 inches.

The correct answer is B. 12 inches.
