My answer: She has wit, charm, and personality.
Teacher's answer: She has wit, charm, and pleasant personality.
Either way, I'd personally go without the
comma after the word "charm", although you (or perhaps your teacher) obviously sit in the Oxonian camp on this somewhat divided issue.
(Also, if your teacher has a problem with losing the "pleasant" qualifier, I'd be tempted to ask why the noted degree of "extremely" still has to be lost. Except that parallelism would now be a matter of just removing "...she has..." from the middle.)
((And, if I had my way, the comma after "charm", as noted. With the "original" obviously needing to have been "She has wit
and charm,[clause-break-comma] and she has...<etc>".))
Levi: My snap judgement would be to say #s 2 or 3. Neither #1 nor #2, as I'd be expecting a possessive, such as "The Butters'[s]
children are good fellows", or similar.
(Today I saw a sign advertising "Kid's go free to <attraction>", or similar, in the window of a shop I was walking past. There was a member of staff in the doorway so I asked him why, and he sighed and agreed. It was too professional a sign (maybe even sent from head office of this chain) to be an
Arkwright-style trick of a sign to attract people inside, starting off as a correcting busybody and ending up as a customer... And neither was the "Britains' [sic] favourite store" sign (actually, a set of large wall-attached letters/punctuations, which should have been easy to reposition correctly with a step-ladder tools and maybe some plaster-filler into the old screw-holes!) once displayed
inside a certain chain-store outlet of my acquaintance (above the entry/exit doors, but on the inside) for at least two years.)
((Non-grammatically, I've also told several supermarket staff, at various different times, about a product where there's at least three different sub-varieties on the shelf, all of which are boxes of five items of identical weight. There's a
price per 100g indicator on the shelf's price-label, which I normally don't take too much notice of when not
specifically looking for the best value between brands. But one day I noticed that two of them are calculated correctly (using something like five bars at 23g, or 115g in all, as a basis for the calculation against the total price of a box) but one of them assumes 5x
115g as the net box weight, and thus a price per mass that is off by a factor of five (and 'better'). It is so displayed in at least three different branches of the supermarket, so Head Office or the central warehouse probably need to edit their master product database. It's been months since I first told my first aisle-based store-worker, and nothing's been done about it (I was tempted to swipe the label to see if it ever got reprinted and replaced correctly, but haven't yet). But I fear I digress, on this point.))
