Show answer & explanation

Explanation
The correct answer is option 3 i.e. 12.
In shooting sports, the shotgun is commonly referred to as a 12-gauge firearm, which has a calibre of approximately 18.5 millimetres. The gauge is a unit of measurement that indicates the internal diameter of the shotgun barrel and is based on the number of lead balls of that diameter required to make one pound. A 12-gauge shotgun means that 12 lead balls of the barrel’s diameter would weigh one pound. This gauge size is popular for hunting and sporting because it offers a good balance of power, range, and recoil, making it suitable for various shooting disciplines.
