Sodium Hydroxide is a strong base with a pH of around 10.5 -11.5. This means it has a high concentration of hydroxide ions and low concentration of hydrogen ions. Options B, C, and D have a lower pH, which indicates a higher concentration of hydrogen ions and a more acidic solution. This does not match the properties of Sodium Hydroxide, making them incorrect options. Additionally, option B falls within the neutral pH range of 7, which is not accurate for a strong base such as Sodium Hydroxide. Therefore, option A is the most accurate and likely the correct answer.
