Match the type of interaction in column A with the distance dependence of their interaction energy in column B :
`{:(,A,,B),((I),"ion-ion",(a),(1)/(r)),((II),"dipole-dipole",(b),(1)/(r^(2))),((III),"London dispersion",(c),(1)/(r^(3))),(,,(d),(1)/(r^(6))):}`

Options

A. (I)-(a), (II)-(b), (III)-(d)
B. (I)-(a), (II)-(b), (III)-(c)
C. (I)-(a), (II)-(c), (III)-(d)
D. (I)-(a), (II)-(c), (III)-(b)

Explanation

To solve the problem of matching the types of interactions in column A with their distance dependence of interaction energy in column B, we will analyze each interaction type and its corresponding distance dependence.

### Step-by-Step Solution:

1. **Identify Ion-Ion Interaction**:
- Ion-ion interactions occur between charged ions (e.g., Na⁺ and Cl⁻ in NaCl).
- The interaction energy is inversely proportional to the distance between the ions.
- The relationship is given by:
...
