Not required

The correct answer is: 3-4 times

In laboratory procedures, it is important to accurately follow the instructions for the best results. This question is asking about the required number of inversions for the Light Blue tube. Option A and C are not the best answers for this question, as they suggest a range that may not accurately fulfill the requirements. Option D is incorrect because many laboratory procedures do require a specific number of inversions in order to properly mix the contents of the tube. Therefore, option B, which specifies the exact number of inversions needed, is the most suitable answer.
