While researching a topic, a student has taken the following notes:

In the Electoral College system that determines the outcome of US presidential elections, the winner of Delaware’s popular vote receives all 3 of Delaware’s electoral votes.
A 2001 article written by law professors Akhil and Vikram Amar proposed that states could instead agree to award their electoral votes to the winner of the national popular vote.
The Amars’ idea is the basis of the National Popular Vote Interstate Compact (NPVIC).
If states holding a majority of electoral college votes (270) adopt the NPVIC, the compact will take effect and adopters will award their electoral votes accordingly.
Delaware adopted the NPVIC in 2019.

The student wants to explain the significance of Delaware’s NPVIC adoption. Which choice most effectively uses relevant information from the notes to accomplish this goal?

An agreement among US states to award their electoral votes to the presidential candidate who wins the national popular vote was adopted by Delaware in 2019.

If the NPVIC takes effect, adopter Delaware will award all 3 of its electoral votes to the winner of the national, rather than the state’s, popular vote.

Because it has adopted the NPVIC, Delaware will award its electoral votes to the winner of the state’s popular vote—once states holding a majority of electoral college votes (270) do the same.

According to the idea proposed by the Amars, the winner of Delaware’s popular vote will receive all of the state’s electoral votes if the NPVIC takes effect.
