A person with a liberal outlook is most likely to be:

A person with a liberal outlook typically embodies progressive thinking, characterized by a willingness to embrace new ideas and approaches. This mindset often involves supporting reform, social justice, and change that promotes individual freedoms and rights. Thus, being encouraging of new ideas aligns perfectly with the definition of a liberal perspective, as it suggests a proactive stance towards innovation and the evolution of thoughts or social norms.

In contrast, the other options describe attitudes that do not align with liberalism. For instance, being open to traditional values reflects a more conservative viewpoint, which tends to prioritize established customs over new ideas. Similarly, resistance to societal change and being fixed in beliefs indicates a reluctance to adopt new perspectives, again contrasting with the essence of a liberal outlook that prioritizes adaptability and the acceptance of progress.
