Which statement most accurately describes a major criticism of the electoral college system

"The Electoral College", set out in Article II, Section 1 of the U.S. Constitution, allows states to have the same power of votes in spite of their number of population.

Due to that, a party could outcast the presidential candidate they don't want, even if such candidate was elected by the majority.

The parties nominate electors, usually by a central committee or the conventions; so when voters cast their ballot for President, they are actually voting for their "State's Electors", who are not obliged to follow the results of the popular vote, thus sometimes “faithless electors” adversely choose a candidate they're not committed to.

A "faithless elector" is simply a member of the "Electoral College" who votes against the party's candidate.  

Thereby the answer is (B): "It allows for faithless electors, or electors who do not vote according to the wishes of their states"
