What are the typical colors and alcohol by volume (abv) of futsu-shu?

Futsu-shu, or ordinary sake, typically exhibits a broad range of colors and alcohol by volume (ABV). The right choice describes futsu-shu as having a color that can be colorless, pale yellow, or green, which aligns with its general appearance. Additionally, the ABV of 15-17% is characteristic for futsu-shu, which often has a higher alcohol content compared to other sake types, particularly due to the inclusion of more rice and fermentation processes used in its production.

In contrast, the other options include colors and ABV ranges that do not accurately reflect futsu-shu's characteristics. For example, darker colors or ABV levels exceeding the 15-17% range would not typically be associated with this particular type of sake, as higher ABV is more aligned with premium or specific sake variants, such as honjozo or ginjo styles.
