Wordpress - Custom Fields and Meta Data

ADelete the option first, then add_option()

BCall add_option() then update_option() unconditionally

CCheck if option exists with get_option(), then add or update

DUse update_option() directly without add_option()

Step 1: Understand update_option behavior
update_option() adds the option if it does not exist, or updates it if it does.
