Step-by-step explanation:
D. Two early political factions developed into political parties in John Adams' presidency, but official parties didn't begin until the early-1800s.
This is because although there were two political factions (the Federalists and the Democratic-Republicans) during Thomas Jefferson's presidency, it was not until the presidency of John Adams that the two factions officially developed into the two major political parties that we know today - the Democratic Party and the Republican Party. Furthermore, it was not until the early 1800s that these two parties began to gain traction and officially become the two major parties that we know today.
