Which of the following statements represents an opinion?

The statement that chocolate ice cream is the best flavor represents an opinion because it expresses a personal preference rather than an objective fact. Opinions are subjective and can vary from person to person, reflecting individual tastes, beliefs, and interpretations. In contrast, the other statements present factual information that can be verified. For example, water boiling at 100 degrees Celsius is a scientific fact under standard atmospheric conditions, and the sun rising in the east is a basic astronomical fact. The last statement about selling seashells is a tongue twister and does not convey an opinion or preference. Therefore, the statement about chocolate ice cream being the best flavor is clearly an opinion due to its reliance on personal preference.
