**Why the Correct Answer is Right**
The vaccine strain used in the Mumps vaccine is the Jeryl Lynn strain, which was isolated from the daughter of Dr. Maurice Hilleman, a renowned virologist. This strain was chosen for its ability to induce a strong immune response while causing mild or no symptoms in vaccine recipients. The Jeryl Lynn strain is a mutated form of the Mumps virus that has been attenuated through multiple passages in cell culture, making it safe for use in vaccines.
**Why Each Wrong Option is Incorrect**

**Option B:** This option may refer to a different vaccine strain, but it is not the correct strain used in the Mumps vaccine.
**Option C:** This option is also a distractor, as it does not correspond to a known Mumps vaccine strain.
**Clinical Pearl / High-Yield Fact**
The Jeryl Lynn strain of the Mumps virus has been used in Mumps vaccines since the 1960s, and it remains the standard vaccine strain used today. This strain has been shown to be highly effective in preventing Mumps disease, and it has played a crucial role in controlling Mumps outbreaks worldwide.
