The Correct Option is B
Approach Solution - 1
To solve the given problem, we need to match the items in List-I with their corresponding descriptions in List-II based on the properties of those substances.
| List-I | List-II | ||
| A. | Coke | I. | Carbon atoms are sp3 hybridized. |
| B. | Diamond | II. | Used as a dry lubricant. |
| C. | Fullerene | III. | Used as a reducing agent. |
| D. | Graphite | IV. | Cage like molecules |
Let's match each item:
- Coke: Used as a reducing agent, typically in metallurgical processes. Therefore, Coke matches with III.
- Diamond: In diamond, carbon atoms are sp3 hybridized and form a very hard structure. Thus, Diamond matches with I.
- Fullerene: Fullerene molecules have a cage-like structure. Hence, Fullerene corresponds with IV.
- Graphite: Known for its layered structure, Graphite is used as a dry lubricant. So, Graphite matches with II.
Therefore, the correct matching is:
A-III, B-I, C-IV, D-II

Approach Solution -2
Coke: In carbon reduction techniques, it serves as a reducing agent.
Diamond: Each carbon atom in a diamond is sp3 hybridized, making it an allotrope of carbon.
Fullerene: Pentagonal and hexagonal rings (a structure resembling a cage) are present in fullerene.
Graphite: Because graphite layers are joined together by feeble Vander Wall attractions, it is a soft solid.
Therefore, The correct option is (B): A-III, B-I, C-IV, D-II

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
