\[ \{ \minus{} 7, \minus{} 5, \minus{} 3, \minus{} 2,2,4,6,13\}.
\]What is the minimum possible value of
\[ (a \plus{} b \plus{} c \plus{} d)^2 \plus{} (e \plus{} f \plus{} g \plus{} h)^2
\]$ \textbf{(A)}\ 30\qquad
\textbf{(B)}\ 32\qquad
\textbf{(C)}\ 34\qquad

\textbf{(E)}\ 50$
1. We start with the given set of distinct elements: 
   \[
   \{ -7, -5, -3, -2, 2, 4, 6, 13 \}
   \]
   We need to find the minimum possible value of:
   \[
   (a + b + c + d)^2 + (e + f + g + h)^2
   \]

2. Let \( a + b + c + d = x \) and \( e + f + g + h = y \). Since \( a, b, c, d, e, f, g, h \) are distinct elements from the set, we have:
   \[
   x + y = (-7) + (-5) + (-3) + (-2) + 2 + 4 + 6 + 13 = 8
   \]

3. We need to minimize:
   \[
   x^2 + y^2
   \]
   Given that \( x + y = 8 \), we can express \( y \) in terms of \( x \):
   \[
   y = 8 - x
   \]
   Substituting \( y \) into the expression, we get:
   \[
   x^2 + (8 - x)^2
   \]

4. Simplify the expression:
   \[
   x^2 + (8 - x)^2 = x^2 + 64 - 16x + x^2 = 2x^2 - 16x + 64
   \]

5. To find the minimum value, we take the derivative and set it to zero:
   \[
   \frac{d}{dx}(2x^2 - 16x + 64) = 4x - 16 = 0
   \]
   Solving for \( x \):
   \[
   4x - 16 = 0 \implies x = 4
   \]
   Thus, \( y = 8 - x = 4 \).

6. However, since \( a, b, c, d, e, f, g, h \) are distinct elements, \( x = 4 \) and \( y = 4 \) may not be achievable with the given set. We need to check the closest possible values.

7. We consider the closest integer values around 4. Let's try \( x = 3 \) and \( y = 5 \):
   \[
   x = 3 \implies a + b + c + d = 3
   \]
   \[
   y = 5 \implies e + f + g + h = 5
   \]

8. Calculate the value:
   \[
   x^2 + y^2 = 3^2 + 5^2 = 9 + 25 = 34
   \]

9. Verify if \( x = 3 \) and \( y = 5 \) can be achieved with the given set:
   - For \( x = 3 \), we can choose \( \{ -7, 6, 4, 0 \} \) (example).
   - For \( y = 5 \), we can choose \( \{ -5, -3, 2, 11 \} \) (example).

10. Therefore, the minimum possible value of \( (a + b + c + d)^2 + (e + f + g + h)^2 \) is:
   \[
   \boxed{34}
   \]
