What are the ways that a republican state chairman can become a member of his party's national committee? select all that apply. if most members in the congress from his states are republican if his state has a republican governor by paying party dues his state cast electoral votes in the last election for the republican candidate by applying for membership

I would say that the correct options are: 
*if most members in the Congress from his states are Republican;
*if his state has a Republican governor
*his state cast electoral votes in the last election for the Republican candidate.

It is important to mention that the chairman has many relevant duties at a national level, for example, to manage public relations and campaigns and assess the President.
