The word "futile" refers to something that is pointless or ineffective, meaning that it does not produce the desired result or has no significant outcome. It conveys a sense of effort that leads to no practical value or success. For example, if someone engages in a futile attempt to resolve a problem that is insurmountable, their efforts will ultimately be unproductive.

In this context, the other options imply meanings that suggest success or effectiveness, which contradict the inherent meaning of "futile." To truly grasp the concept of futility, one must acknowledge that it denotes a lack of purpose or successful result in an endeavor. Thus, choosing the description of "pointless and ineffective" accurately captures the essence of what it means for an effort to be deemed futile.
