Choose the answer that represents the time 7: 30 p. m. il est sept heures et demie du matin. il est sept heures vingt du soir. il est sept heures et demie du soir. il est sept heures trente du soir.

Hi !!

7:30 p.m. = Il est sept heures et demie du soir.

sept heures trente is correct as well, but I think , at school, you've to learn "et quart" , "moins le quart", "et demie"
As in French school , we have to learn the proper way to say the hours as "it's half past seven p.m." and not "seven thirty" even though , it's used

hope I helped !!
