Horizontal power sharing distributes power across different governmental branches at the same level. India's government exemplifies this, dividing power between the Legislative, Executive, and Judiciary branches. This prevents any single branch from gaining excessive power, fostering a system of checks and balances. This arrangement is fundamental to the Indian Constitution's governance structure.
Conclusion.
The Legislative, Executive, and Judiciary's power division represents horizontal power sharing, making option (D) the correct answer.
