Right!

Which marks of punctuation would be appropriate to set off the italicized words in the following

sentence? One day my dad and his brother stop me if you've heard this story started out on what they
thought would be an uneventful drive to work.

Father's in law

Yes, you are correct. The correct plural form of the noun "father-in-law" is "fathers-in-law" (option A).

To determine the correct plural spelling, you generally add an "s" or "es" to the end of the singular noun. In this case, we have a compound noun formed by combining "father" and "in-law." When making a compound noun plural, we make the main part of the compound (in this case, "father") plural, while leaving the other part ("in-law") singular.

So, "father-in-law" becomes "fathers-in-law." The other options are incorrect because "editor in chiefs" should be "editors in chief," "phenomenon" should be "phenomena," and "piano" should be "pianos."
