The group of elements that is commonly used as dopants in extrinsic semiconductors is:

b. Group III and V elements.

Explanation:

1. Group III Elements: These elements, which include boron (B), aluminum (Al), gallium (Ga), and indium (In), are known as p-type dopants. When added to a semiconductor (like silicon), they create 'holes' by accepting electrons from the conduction band, thus increasing the number of positive charge carriers.

2. Group V Elements: These elements, such as phosphorus (P), arsenic (As), and antimony (Sb), are known as n-type dopants. They provide additional electrons that can participate in conduction when introduced into a semiconductor, enhancing the material's conductivity.

In summary, both Group III and Group V elements play a vital role in adjusting the electrical properties of semiconductors, making them essential for the development of various electronic devices.
