D. `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(1)4p^(6)`

Explanation

To find the electronic configuration of the element just above the element with atomic number 43 in the same periodic group, we will follow these steps:

### Step 1: Identify the Element with Atomic Number 43
The element with atomic number 43 is Technetium (Tc).

### Step 2: Determine the Position of Technetium in the Periodic Table
Technetium (Tc) is located in Group 7 and Period 5 of the periodic table.

### Step 3: Identify the Element Above Technetium
The element directly above Technetium in Group 7 is Manganese (Mn), which has atomic number 25.

### Step 4: Write the Electronic Configuration of Manganese
The electronic configuration of Manganese (Mn) can be determined as follows:
- The atomic number of Manganese is 25.
- The electronic configuration is built up according to the Aufbau principle:
- 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵.

Thus, the electronic configuration of Manganese is:
**1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵**.

### Final Answer
The electronic configuration of the element just above the element with atomic number 43 (Technetium) in the same periodic group is:
**1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵**.
