LOX color?

Explanation:
This question tests your ability to recognize the color of LOX, which is liquid oxygen. Liquid oxygen has a pale blue tint when viewed in its cryogenic containers, commonly described as light blue. The other options don’t fit what LOX looks like in its liquid form: deep blue would be a much stronger tint than is typical; green isn’t used to indicate LOX; and clear would mean no color at all, which isn’t the case for LOX liquid. In practice, equipment and signage for LOX are color-coded blue to help crews identify oxygen service quickly. So, light blue is the correct color.
