What does the term 'impeccable' mean?

The term 'impeccable' refers to something that is flawless and exhibits perfection or is beyond reproach. When something is described as impeccable, it means it has been performed or executed to the highest standards without any errors or shortcomings. In this context, the correct answer indicates that the action or object in question has been completed so flawlessly that it is considered perfect.

In contrast, the other options present definitions that do not align with the meaning of 'impeccable.' For instance, describing something as common or average implies mediocrity, which is the opposite of perfection. Similarly, stating that something is full of flaws directly contradicts the idea of being impeccable, as it suggests faults and imperfections. Lastly, labeling something as very difficult does not relate to the quality of execution or performance, further distinguishing it from the intended meaning of 'impeccable.'
