Which statement correctly describes an electrode in a voltaic cell of copper and hydrogen?

-Copper atoms become copper ions at the anode because the SRP is more positive.

-Hydrogen ions become diatomic hydrogen at the cathode because hydrogen is always reduced in a voltaic cell.

-Copper ions become copper atoms at the cathode because copper is always reduced in a voltaic cell.

-Diatomic hydrogen becomes hydrogen ions at the anode because the SRP is more negative.

I think the correct answer is the third option. Copper ions become copper atoms at the cathode because copper is always reduced in a voltaic cell. In a cathode of a voltaic cell, reduction of copper ions happen. Two electrons are added making it a neutral atom of copper.
