Answer: (A)

Verified step by step guidance

1. Understand that metalloids are elements with properties intermediate between metals and nonmetals.
2. Recall the layout of the periodic table, where metals are generally on the left and center, and nonmetals are on the right.
3. Identify the zig-zag (stair-step) line on the periodic table, which acts as a boundary separating metals and nonmetals.
4. Recognize that most metalloids are located along this zig-zag line, reflecting their intermediate properties.
5. Conclude that the best description of the location of most metalloids is that they are found along the zig-zag (stair-step) line that separates metals and nonmetals.
