Answer 1

Correct option is (b) Cold cranking amps

Explanation: Today’s batteries are rated in term of cold cranking amps. This represents the current that the battery can produce for 30 seconds at 0^oC before the battery voltage drops below 7.2 volts. An average battery today will have a CCA (Cold Cranking Amps) of 500.
