What is the correct sequence of steps to determine the R or S configuration of a chiral center?

Assign priorities based on atomic mass, orient the molecule with the highest priority group in the back, and trace the path from lowest to highest priority.

Assign priorities based on bond strength, orient the molecule with the lowest priority group in the front, and trace the path from highest to lowest priority.

Assign priorities based on atomic number, orient the molecule with the lowest priority group in the back, and trace the path from highest to lowest priority.

Assign priorities based on bond length, orient the molecule with the highest priority group in the front, and trace the path from lowest to highest priority.
