Ответ:
The correct answer is B. Metalloids
Explanation:
In this periodic table, the green boxes include elements such as Boron (B), Arsenic (As), and Antimony (Sb). All these elements are known in chemistry as semimetals or metalloids. This classification is because these elements cannot be completely classified into metals or non-metals. Moreover, they all display similar properties including some level of conductivity, malleability, and solid-state. According to this, the correct answer is B.
