Which of the following best describes "onerous" tasks?

The term "onerous" is derived from the word "oner," which indicates a burden or a weight. It specifically refers to tasks that are burdensome, demanding, or troublesome, often requiring significant effort and causing a sense of strain or fatigue. Therefore, describing "onerous" tasks as burdensome and tedious accurately encapsulates their nature, as these tasks typically require more effort than one might desire and often do not yield fulfilling results.

The other choices do not align with this definition. For instance, calling tasks enjoyable and fulfilling (the first choice) contradicts the essence of something that is onerous, as those descriptions imply positivity and satisfaction—qualities that onerous tasks lack. Similarly, describing them as inconsequential and easy (the second choice) or simple and straightforward (the last choice) also fails to capture the inherent difficulty and undesirable quality associated with onerous tasks. Overall, the correct answer encapsulates the demanding nature of onerous work effectively.
