Answer & Solution
Option: C
Explanation :The IMEI (International Mobile Equipment Identity) number is a unique set of 15 digits used on GSM phones to identify them. Because the SIM card is associated with the user and can be swapped from phone to phone, a method is needed to keep track of the hardware itself, and that’s why the IMEI was developed. The first 14 digits are decided by the GSM association, and the final check digit is computed using what’s called the Luhn Formula — crazy base-8 math that mere mortals like most of us don’t understand, nor want to understand.
