Best answer
The correct option is (a) Cold-cranking amperes

For explanation I would say: The abbreviation of CCA is cold cranking amperes. The CCA rating of an automobile battery must equal or exceed the number of cubic inches of engine displacement. The temperature of the cold rate or CCA of the battery at the beginning of discharge is kept -18 degrees centigrade.
