The correct statement and conclusion about sodium hydroxide is:

Sodium hydroxide is a strong base with a large number of OH- ions.

Sodium hydroxide (NaOH) dissociates completely in water to produce a high concentration of hydroxide ions (OH-), which is why the pH reaches 12. This indicates a basic solution.
