What stance did Carol's dad take regarding her tattoo?

The reasoning behind the correct choice lies in the phrase "drew the line," which indicates that Carol's dad had a definitive stance against her having a tattoo. This expression suggests that there were boundaries or limits to what he was willing to accept in terms of her personal choices. By choosing this option, it underscores the idea that he did not approve of the tattoo, signaling a firm position on the matter.

In contrast, the other options imply varying degrees of acceptance that do not align with the idea of setting a limit. For instance, if he fully supported it, that would indicate a positive endorsement rather than a boundary. Similarly, having no opinion would suggest indifference, and liking the tattoo would also reflect a level of approval rather than disapproval. Thus, the correct answer effectively captures the essence of his reaction and illustrates the dynamics of their relationship concerning personal expression.
