viii. Which is likely to show inert pair effict ?

Options

A. `K`
B. `Mg`
C. `Al`
D. `Pb`

Explanation

To determine which element is likely to show the inert pair effect, we need to understand what the inert pair effect is and how it relates to the elements in the p-block of the periodic table, specifically in Group 14.

### Step-by-Step Solution:

1. **Understanding Inert Pair Effect**:
- The inert pair effect refers to the tendency of the outermost s-electrons (specifically the s-electrons in the outermost shell) of heavier post-transition metals to remain non-ionized or unshared in chemical reactions. This effect is more pronounced in heavier elements of groups 13, 14, and 15.

2. **Identifying the Group**:
