In which of the following is the ceremonial and executive powers fused?

The parliamentary system of government is the system where the ceremonial and executive powers are fused. In this system, the head of state, who is usually a monarch or a president with ceremonial powers, and the head of government, who is the prime minister with executive powers, are part of the same institution (parliament). This means that the prime minister is accountable to the parliament for the actions of the government, and can be removed from office by a vote of no confidence. The parliamentary system is different from the presidential system of government, where the head of state and head of government are separate institutions.
