{'bases': [0, 0, 1, 1], 'code glven': [0, 0, 1, 0], 'magnesium': [1, 0, 2, 3], 'aluminium': [1, 0, 3, 2], 'ammonium': [0, 0, 2, 0], 'sodium': [10, 2, 12, 23], 'order': [6, 12, 34, 35], 'basic strength': [0, 0, 1, 0]}

The correct answer is option 3 which is 4-3-2-1.

To understand why, let`s look at the basic strength of each compound:

1. Sodium hydroxide (NaOH): Sodium hydroxide is a strong base as it completely ionizes in water, releasing hydroxide ions (OH-) which are responsible for its basicity.

2. Magnesium hydroxide (Mg(OH)2): Magnesium hydroxide is a weak base compared to sodium hydroxide. It does not fully ionize in water and releases fewer hydroxide ions.

3. Aluminium hydroxide (Al(OH)3): Aluminium hydroxide is even weaker as a base compared to magnesium hydroxide. It has even fewer hydroxide ions in solution.

4. Ammonium hydroxide (NH4OH): Ammonium hydroxide is the weakest base among the given compounds. It is a weak base because ammonium ions (NH4+) partially react with water to form fewer hydroxide ions.

Therefore, the increasing order of their basic strength is: Ammonium hydroxide < Aluminium hydroxide < Magnesium hydroxide < Sodium hydroxide.
