he ________ (yellow)
a gases, solids
b metals, nonmetals
c nonmetals, metals
d reactive, nonreactive

Explanation:

In the periodic table, the stair - step line (also known as the metalloid line) separates nonmetals (usually on the right, often represented in yellow in some visualizations) from metals (usually on the left, often represented in pink). Option A is incorrect because the stair - step line does not separate gases and solids. Option D is incorrect as it does not relate to reactivity in this way. Option C has the order reversed. So the correct answer is B.

Answer:

B. metals, nonmetals
