The group of elements that is generally unreactive is B. Noble gases.

Here's why:

Noble gases, which include helium, neon, argon, krypton, xenon, and radon, are located in Group 18 of the periodic table. These gases are known for being colorless, odorless, tasteless, and nonflammable.

The key reason they are generally unreactive is due to their electron configuration. They have a full set of electrons in their outermost energy level, which means they are stable and have no tendency to gain, lose, or share electrons. This makes them very unreactive compared to other elements.

In contrast, other groups like halogens (Group 17) and alkali metals (Group 1) are very reactive as they have one less or one more electron than a stable configuration, which makes them more likely to engage in chemical reactions to achieve stability. The nitrogen family (Group 15) also tends to be reactive as they have five valence electrons and need three more to reach a stable configuration.
