Answer : 2. "Sodium hydroxide"
Explanation :
The correct answer is Sodium hydroxide. Sodium hydroxide is considered a strong base as all the available [OH] in NaOH is present in the solution as [OH−] and available to accept protons. Sodium hydroxide is the strongest base because it totally dissociates to form sodium ions and hydroxide ions.
