I'm playing Massenet's "Meditation" from Thais in an informal concert at an old people's home on Saturday: I learned this years ago but have forgotten haow to play the last note (a harmonic) correctly - its printed as one of those diamond- shaped stopped harmonics on the 3rd finger 1st position D on the A string, but I can't remember whether that means
a) lightly stop the A string at this position, producing (? haven't got my violin here to check!)) a high A 2 octaves above the A string

stop the D with the 1st finger & put the 4th finger lightly down to get the high D harmonic
c) something else!
I suspect it's

because that means the piece ends on the key-note, but I also have memories of struggling to find a clear tone wnen I last played this in public! - hopefully I've improved since!
Any advice gratefully received
