In the question below, fill the gap with the most appropriate option:
They spent the last holiday with their _____
Answer Details
The correct option is "sisters-in-law."
When referring to the family members of one's spouse, the correct term is "in-law." In this case, the plural form "sisters-in-law" is appropriate, as it refers to more than one sister of the spouse.
It's important to note that "sisters-in-laws" and "sisters-inlaw" are not grammatically correct. Adding an "s" to "in-law" makes the word "laws" plural, which doesn't make sense in this context. Combining "sisters" and "in-law" into one word is also not correct.
