(b) Introduction of double government i.e., Central and State governments.

(c) Having two sets of rulers; one in London and another in Delhi.

Answer: (d)

Explanation:

• Under this system, certain subjects such as finance and law and order were designated as ‘reserved’ subjects and remained under the direct control of the Governor.
• On the other hand, subjects such as education, public health, and local self-government were designated as ‘transferred’ subjects, which were to be controlled by ministers accountable to the Legislatures.
