Certainly! Let's find which element is in the same group of the Periodic Table as lithium based on the given options.

We know lithium is an alkali metal, which is a group characterized by its high reactivity and low density.

The elements given in the table along with their properties are:

| Element | Electrical Conductivity | Density (g/cm³) |
|---------|-------------------------|-----------------|
| A | High | 0.97 |
| B | High | 8.93 |
| C | Low | 0.07 |
| D | Low | 3.12 |

From this information:
- Element A has high electrical conductivity and a density of 0.97 g/cm³.
- Element B has high electrical conductivity and a density of 8.93 g/cm³.
- Element C has low electrical conductivity and a density of 0.07 g/cm³.
- Element D has low electrical conductivity and a density of 3.12 g/cm³.

Given that lithium is an alkali metal, it typically has high electrical conductivity and a low density. Among the elements listed, the one that also has high electrical conductivity and a relatively low density (closer to the properties of lithium) is:

- Element A: High electrical conductivity, 0.97 g/cm³

Therefore, the element in the same group of the Periodic Table as lithium is:
