What best defines the term "tyrannical"?

The term "tyrannical" is best defined as characteristic of a harsh ruler, which captures the essence of authoritarian governance where power is concentrated in the hands of a single leader who often rules in an oppressive and cruel manner. Tyrannical leaders typically do not tolerate dissent or opposition, and their rule is marked by the abuse of power, leading to a climate of fear and repression among the populace.

In contrast, democratic rule signifies governance through elected representatives and is fundamentally opposite to tyranny. Kind leadership implies a nurturing and supportive approach to leading a group, which is inconsistent with the harshness associated with tyranny. Fair administration refers to a just and equitable management of governance, directly opposing the ideas of oppression and injustice that are inherent in tyrannical leadership. Thus, the definition of "tyrannical" aligns squarely with the notion of a harsh ruler, making it the correct choice.
