Which of the following BEST explains why the 25th Amendment was first used?

The 25th Amendment was ratified in 1967 and was first used in 1973, when Vice President Spiro Agnew resigned. President Nixon nominated Gerald Ford to fill the vice-presidential vacancy, and Congress confirmed him under Section 2 of the amendment. The correct choice is “It was used to fill the vacancy left after the resignation of Vice President Agnew during the Nixon Administration.” Kennedy’s assassination and Nixon’s resignation happened before the amendment was in effect or did not trigger its first use.
