The full name expansion for the valve abbreviated OS&Y is which of the following?

Explanation:
OS&Y stands for Outside Stem and Yoke. This design has the valve stem protruding outside the valve body and connected to a yoke at the top. Because the stem is visible, you can easily tell whether the valve is open or closed by observing the stem’s position. The term does not include a cap, so options that add “cap” don’t fit the standard expansion. The familiar phrasing is Outside-stem-and-yoke valve.
