AI Explanation
The correct answer is C) light blue. The color-coding for a storage container of R-134a refrigerant is light blue. This is in accordance with the color-coding standards established by the Occupational Safety and Health Administration (OSHA) for the identification of refrigerants. R-134a, a commonly used refrigerant, is assigned the light blue color code. The other answer choices are incorrect because green is typically used for oxygen, purple is used for ammonia refrigerant, and grey is not an established color code for refrigerants.
