Explanation:

- The Indian Constitution sets a limit on the size of the Council of Ministers for the National Capital Territory (NCT) of Delhi.

- According to Article 239AA(4), the Council of Ministers—including the Chief Minister—can’t be more than 10% (that’s one-tenth) of the total number of members in Delhi’s Legislative Assembly.

- Let’s check the options:

- 0.05 (5%)—Nope, that’s not the limit.

- 0.15 (15%)—Too high, not correct.

- 0.2 (20%)—Also too high, not the answer.

- 0.1 (10%)— Yes, this matches what’s in the Constitution.

- What this means: If Delhi’s Legislative Assembly has, say, 70 members, then the Council of Ministers can’t have more than 7.

- So, 0.1 (10%) is definitely the right answer here.
