What is the meaning of the term obviate?

The term "obviate" means to prevent or make something unnecessary. It is often used in contexts where an action or solution removes the need for something else to occur. In this sense, when one takes steps to obviate a problem, they effectively eliminate the necessity of addressing that problem later on. This aligns precisely with the definition of rendering something unnecessary, making it the correct choice among the options provided.

The other terms do not capture the essence of "obviate." For instance, rendering necessary would contradict the meaning, as it suggests the opposite effect. Similarly, to obscure means to make something less visible or clear, which is unrelated to the concept of preventing necessity. Illustrating further pertains to expanding on an idea or explanation but does not relate to making something unnecessary. Therefore, the definition aligns perfectly with the meaning of the term.
