Which sentence correctly uses an objective case pronoun?
a. the two drummers in the band are carrie and him.
b. the rain kept him and his friends inside all afternoon.
c. us and julie made this card for grandma.
d. have them listened to the governor’s speech?

The correct sentence is B. The rain kept him and his friends inside all afternoon. A is incorrect because it should be Carrie and he (just change the order of the words into: He and Carrie are the two drummers in the band - and you'll see that using him is incorrect). C is incorrect because it should be we, not us. D is incorrect because it should be they, not them.

The error in the sentence is a dangling modifier
