What characteristic is likely associated with a "miser"?

The answer is accurate because a "miser" is typically defined as a person who hoards wealth and spends as little money as possible, often to the point of avoiding essential expenditures. This behavior reflects a tendency to save greedily rather than invest or spend, even when it might be reasonable to do so. Misers are often described as excessively frugal, prioritizing the accumulation of wealth over enjoying life or helping others.

In the context of the other options, generosity is the opposite of a miser's behavior, as it implies a willingness to share or give freely. Wastefulness also contrasts sharply with miserly behavior, as it involves spending or using resources carelessly rather than being frugal. A willingness to spend, which suggests a propensity to spend money freely, is definingly at odds with the core nature of a miser, who avoids spending at all costs. Thus, the characteristic associated with a miser is indeed a tendency to save greedily.
