Step 1: Identify the coordinates of points S and T
From the figure, point S is located at -5 and point T is located at 0.
Step 2: Calculate the distance between points S and T
The distance between two points on a number line is the absolute value of the difference between their coordinates. Therefore, the distance \( ST \) is:
\[ |T - S| = |0 - (-5)| = |0 + 5| = 5 \]
Final Answer
The length of segment \( ST \) is 5.
Since 5 is not listed among the options, the correct answer is:
