How do you spell the plural of waltz a. waltzs b. walzez c. waltz's d. waltzes

we can spell waltz as an waltzes

so the answer is D. waltzes.

D. You can Waltz once, then you can do lots of kinds of waltzes.  It's not A because we have a z at the end and that would make it sound the same. Not B because if you're aiming for plural words, we never put Zs. Can't be C because that would make it in possession. eg; That's the Waltz's song. Therefore, it must be D.

3 is blunder, i’m not sure about the last one but the first two look correct
