Which adjective best describes something that is "patent" in terms of visibility?

The adjective "patent" refers to something that is clearly visible or obvious. When something is described as patent, it implies that it is open to view and easily perceptible, lacking any ambiguity or obscurity. This aligns perfectly with the choice of "open to view," as it emphasizes clarity and visibility. The other options do not convey the same meaning; for instance, "unyielding" suggests a hardness or stubbornness, "minute" connotes something small or insignificant, and "fighting against" implies a sense of opposition or resistance, all of which are unrelated to the concept of visibility or obviousness. Therefore, "open to view" is the best descriptor for something that is patent.
