The D course rings open in the lowest shape, with the remaining notes fretted at fret 5 over a 2-fret stretch. C falls on the G course. It sounds from C3 up to Bb4.
Octave Mandolin is strung in four courses of two, so each stopped note here sounds as two — which is why the shape rings thicker than the same grip on a single-strung instrument.
