What does the term 'patent' mean in this context?

In this context, 'patent' refers to something that is obvious or readily visible. This meaning aligns with how the word is commonly used in English, particularly in expressions like "patent absurdity," which indicate something that is clearly and unmistakably apparent. The term conveys a sense of clarity and visibility, making it easily understood or noticeable.

The other terms do not fit the context of 'patent.' Obscure suggests something that is hidden or not easily seen, which contradicts the idea of being obvious. Confusing implies a lack of clarity or difficulty in understanding, while exceptional denotes something that is unusually good or outstanding, rather than stating that something is clear or evident. Thus, the choice that best captures the definition of 'patent' in this scenario is obvious; readily visible.
