Answer:
The answer is D. Poor technique, because the spotter should have their hands underneath the bar.
Step-by-step explanation:
Well first we haft to know that while spotting your back has to be straight (removing option B. witch goes agents this statement.) Your hands haft to be inside of the lifters hands and under the bar.
If there were two people, and their is not you would be on the side of the bar cupping two hands under the bar moving up and down with it. (this removes option C.)
