When realizing a figured bass in 4-part writing, what pitch of the triad is most often doubled?

this is a experment where you actully have to do the work like go take some photos in something your interstid in

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.  

answer: your like me reserved loud around those i'm comfortable with, i don't like to be in crowds because i'm not social basically i'm pretty reserved, and also because of a trauma i got lost in an auditorium in between a huge crowd so whenever i'm in a crowd i get anxiety. i cant be apart from my mom even in stores,. i'm not a cheerleader or anything just home drawing, crocheting, baking, my cousin with some video games and his lego creations, watch you tube in my free time love baseball and soccer! my favorite music would be classical, k pop, or just listening to the melodies of the music of the video games. i play the piano a bit im still learning. tho i play pretty good. oh and even around my it weird but it just how it is.. like literally. ( my favorite video game is smash bros ultimate my main is roy)
