What is a synonym for invaluable?

  1. Insignificant

  2. Indispensable

  3. Unnecessary

  4. Obsolete

The correct answer is: Indispensable

The term "invaluable" refers to something that is extremely useful or indispensable, often to the point that its value is beyond measurement. This aligns perfectly with the word "indispensable," which signifies that something is absolutely necessary and cannot be done without. In contexts where something is invaluable, it is often essential to the success or function of a particular situation or task, making "indispensable" a fitting synonym. The other choices do not convey the same meaning. "Insignificant" suggests that something has little or no value, while "unnecessary" implies that something isn’t needed at all. "Obsolete" describes something that is no longer in use or out of date, which further diverges from the meaning of invaluable. Thus, "indispensable" accurately reflects the essence of what it means for something to be invaluable.
