Complete the paragraph with the most appropriate option:
The James Webb Space Telescope (JWST) is stationed approximately 1.5 million kilometers away from Earth at the second Lagrange point (L2). This distant vantage point offers a critical operational advantage. ---- Because its infrared sensors must remain chilled to minus 233 degrees Celsius to avoid heat interference, this permanent shielding is essential for detecting distant, faint galaxies.
