The diastolic murmur due to mitral stenosis is typically accompanied by which feature?

Explanation:
Mitral stenosis causes thickened, restricted mitral leaflets that resist opening during diastole. When the leaflets finally yield and snap open after the second heart sound, a brief high-pitched sound—an opening snap—appears. This opening snap is a classic accompanying sign to the diastolic rumble heard at the apex in MS and helps distinguish it from other conditions. The other options don’t fit because a S2 click isn’t typical of MS, an early systolic murmur isn’t produced by MS, and fixed splitting of S2 is more characteristic of atrial septal defect rather than mitral stenosis.
