Hint: One of the following is the strongest base as it completely dissociates to form sodium ions and hydroxide ions.

Complete step by step answer:
A) Sodium hydroxide is the strongest base because it completely dissociates to form sodium ions and hydroxide ions. These hydroxide ions are treated with hydrogen ions further from the acid and completely ionize the hydrogen ions.
B) Magnesium hydroxide is an inorganic compound having the chemical formula of $Mg{(OH)_2}$ . It forms in nature as the mineral brucite. It is a white colour solid having low solubility in water. Magnesium hydroxide is a very common component of antacids, like milk of magnesia, also just like laxatives.
C) Ammonium hydroxide is generally an ammonia solution of water. Normally referred to as ammonia or ammonia gas, this compound is useful as a cleaner and also in the manufacturing of plastics, rubber, fertilizers and textiles. It does not have any colour, white liquid having a pung-to-faint ammonia smell.
Hence, Option A) $NaOH$ is correct.

Additional information:
- It is the main component in drain and oven cleaners. It is actually used in chemical manufacturing, oil refining, hydraulic fracturing, water treatment and metal processing. It is also useful in the manufacture of fabric, plastic wrap, paper and soap.
- Concentrated sodium hydroxide is a very harmful chemical and can create very serious tissue burns in humans; if it is splashed in the eyes by accident, it could create permanent blindness and many several damages. When it is actually applied to plants, the sodium hydroxide could also damage their tissues and more than likely kill them as well.

Note: Observing the hint and question options, answers can be easily known, also $NaOH$ as completely dissociates to form sodium ions and hydroxide ions, It is the strongest base among the following.
