Answer: (C)

Verified step by step guidance

1. Step 1: Understand the classification of elements in the periodic table. Elements are broadly categorized into metals, nonmetals, and metalloids based on their physical and chemical properties.
2. Step 2: Recall that metals are typically found on the left and center of the periodic table, nonmetals are on the right side, and metalloids lie along the dividing line between metals and nonmetals.
3. Step 3: Recognize that metals constitute the majority of elements in the periodic table, including groups such as alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides.
4. Step 4: Note that nonmetals are fewer in number and include elements like hydrogen, carbon, nitrogen, oxygen, halogens, and noble gases.
5. Step 5: Understand that metalloids have properties intermediate between metals and nonmetals and are relatively few compared to metals and nonmetals.
