"Your mother-in-law is your husband's mother."
Translation:Ta belle-mère est la mère de ton mari.
Are the hyphens optional or not? I answered a previous question and left out the hyphen and was told I had a typo. The word bank questions seem to give a correct answer whether the hyphen is there or not and in this instance, although the correct answer shows a hyphen, there was no hyphenated word to choose.
