Explanation:

The presidential system has several advantages. As the President is selected separately from the Legislature, the President and Executive branch are not subject (in most cases) to any form of vote of noconfidence. As such, this leads to continuity in the Executive branch, as the Executive will remain stable over the term of the President. Besides, there is a clear demarcation between the Executive and the Legislative branch, allowing for a more effective set of checks-and-balances to be placed on both branches by the other. Hence option 2nd is correct.
