A tubular magazine is characterized by its design, where it stores cartridges in a long, narrow tube that typically runs parallel to the barrel of the firearm. This kind of magazine can be located under the barrel or integrated into the stock of the firearm, which is a common configuration for rifles designed for certain types of ammunition, such as .22 caliber rounds.

The location of the tubular magazine is an important feature, as it influences the overall balance and aesthetics of the firearm. It allows for a streamlined design and facilitates the feeding of rounds into the chamber. This makes option B the correct answer, as it accurately describes the fundamental aspect of a tubular magazine’s placement and configuration.

In contrast, a tubular magazine is not limited to holding only revolver cartridges, nor is it designed for one-time use; instead, it's intended for multiple reloads. Additionally, it is typically not external and visible when empty; rather, it's integrated into the firearm's design, which also makes the characteristics of the other options less applicable.
