Which of the following describes when both eyes rotate about the y axis and the upper portion of their eyes rotate to the left during versions?

Explanation:
During versions, the eyes move together, and a torsional component is described as cycloversion. The direction is named by where the top part of the eye rotates. If both eyes rotate so the upper poles move to the left, that is levocycloversion. The other terms describe either no torsion (levoversion, dextroversion) or torsion in the opposite direction (dextrocycloversion).
