Hi there! This question is a bit confusing. 
 Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge. 
Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.
 Your answer would be "Secondary cells are rechargable" 
Have a great rest of your day!
