To find out how much taller the cat is than the dragon, we first need to look at their heights.
- Height of the dragon: 12 inches
- Height of the cat: 78 inches
Now, we can calculate the difference in height:
\[ \text{Height of the cat} - \text{Height of the dragon} = 78, \text{inches} - 12, \text{inches} = 66, \text{inches} \]
However, it seems there may be confusion in the phrasing of the problem or the provided choices. Based on the calculations, the cat is 66 inches taller than the dragon, which does not match any of the options provided.
If we interpret the options differently or if there's a mistake in the figures shared, please clarify. However, based on what's presented, the answer is 66 inches.
