The term "authoritarian" is used to describe a governing or leadership style that centralizes power in one or a few leaders, often with limited political freedoms and a lack of democratic processes. This contrasts with other forms of governance that prioritize individual liberties and collective decision-making. The best synonym among the given options is "autocratic" (A).

"Autocratic" refers specifically to a system where one individual, or a small group, wields considerable control over a state or organization, making unilateral decisions without significant input from others. This aligns closely with the definition of "authoritarian," which emphasizes strict obedience to authority.

In contrast, the other options—"senior," "elderly," and "potential"—do not relate to governance or leadership style. "Senior" and "elderly" refer to age and status rather than political systems, while "potential" pertains to capabilities or future possibilities rather than a specific governing ethos. Thus, "autocratic" stands out as the only appropriate term that accurately captures the essence of authoritarianism.
