To determine the value of angle D, we first need to equate the interior angles at point B and point D if they are part of a specific geometric shape (for instance, a triangle or any polygon). However, we will base our calculations on the information given.
You mentioned that:
- The angle at point B measures (3x - 7) degrees.
- The angle at point D measures (x + 15) degrees.
Assuming that points B and D are angles of the same geometric figure and the interior angles are supplementary or equal, we can set up an equation. However, none of the relationships provided stipulate whether they are equal or supplementary.
Since we do not have complete information about the relationship between these angles, we cannot definitively solve the equations directly.
If we assume they are equal (common in certain geometric formations like a triangle), we can set them as follows:
\[ 3x - 7 = x + 15 \]
Let's solve for x:
1. Subtract \( x \) from both sides:
\[ 3x - x - 7 = 15 \]
\[ 2x - 7 = 15 \]
2. Add 7 to both sides:
\[ 2x = 22 \]
3. Divide by 2:
\[ x = 11 \]
Now, substitute \( x = 11 \) back into the expression for angle D:
\[ D = x + 15 = 11 + 15 = 26 \]
So, the value of angle D is **26 degrees**.
Therefore, the correct response is 26.

Therefore, the correct response is 26.
