One Advantage That a Parliamentary Democracy Has Over a Presidential

One advantage that a parliamentary democracy has over a presidential one is that

A) the person elected as leader of a parliamentary democracy (typically called a prime minister) is always the most popular politician in the nation, so it is easy to find public support for their policies
B) the leader of a parliamentary democracy (typically called a prime minister) has no political ties to members of parliament and so can act more independently than a president often can
C) compromise is typically easier to reach
D) voters feel invested in politics since their votes directly elect the national executive
