I know that V43 is a better option but the exercise I am doing does not allow me the option of inverted 7 chords. Can someone please correct me if I have made a mistake?

Dekka that is not the same at all. In the other question I thought it might be nice to get a list of exceptions going ... that is a general question regarding those two intervals, it just happens to use that progression.– user35708Nov 3, 2021 at 14:33

are the 2notes in the bass line also eighth notes? Are the Roman numbers given or is this your task? If you are free you can treat the melody note C in B-C-D as passing tone.– Albrecht HügliDec 4, 2021 at 12:26

I don't see any problems here! You obviously can't double the F♯, and doubling the bass A would lead to parallels, so your only option is to double the C.
But there is one caveat: some traditions are really strict about motion from a diminished fifth to a perfect fifth, and thus they may view the upper-voice motion (soprano and tenor) moving into the I6 to be an error. I don't remember what Aldwell and Schachter say, but you'll want to clarify that they "allow" this if you're trying to follow that book exactly.
For me, I see this motion far too often in the literature to treat it as a part-writing error. There are chords later on where you can't resolve the tritone "correctly," and for that reason I personally think outlawing d5–P5 motion is pretty unnecessary.

They say that because of the parallel 10ths in the outer voices the D5 is allowed to move to a P5.– user35708Nov 3, 2021 at 10:59
