Diaphragm on one side, bell on the opposite side
Diaphragm Only
Bell on one side, Diaphragm on the opposite side

The Correct Answer is B
A. Diaphragm on one side, bell on the opposite side: Suitable for a full cardiac examination, as it can assess both high and low-frequency sounds.
B. Diaphragm Only: Less suitable for a full cardiac examination because it may not effectively capture low-frequency sounds such as certain heart murmurs.
C. Bell on one side, Diaphragm on the opposite side: Effective for a full cardiac examination, as it can assess both high and low-frequency sounds.
D. Diaphragm and bell on same side: Allows for a complete assessment of heart sounds, though it may be less versatile than separate components on each side.
