{'sodium hydroxide': [0, 0, 0, 1], 'acetic acid': [0, 0, 0, 1], 'hydrochloric acid': [1, 0, 3, 0], 'weak acid': [0, 0, 0, 1], 'strong acid': [0, 0, 0, 1], 'compound': [0, 0, 1, 1], 'calcium oxide': [0, 0, 0, 1], 'base': [3, 0, 3, 6]}

The question is asking us to match compounds from List I with their corresponding nature from List II.

List I contains the compounds:

A. Sodium hydroxide

B. Calcium oxide

C. Acetic acid

D. Hydrochloric acid

List II describes the nature of the compounds:

1. Strong acid

2. Alkali

3. Weak acid

4. Base

The correct match between the compounds and their nature is given by option 2: A, B, C, and D correspond to 2, 2, 4, and 3 respectively.

Let`s dissect the options to understand why the correct answer is option 2:

- Option 1 does not have the correct matches because it pairs sodium hydroxide (which is an alkali) with 1 (strong acid), which is incorrect.

- Option 3 pairs sodium hydroxide with 1 (strong acid) and acetic acid with 3 (weak acid), which is incorrect.

- Option 4 pairs sodium hydroxide with 1 (strong acid) and hydrochloric acid with 4 (base), which is incorrect.

Therefore, option 2 is the correct answer as it correctly matches the compounds from
