At 7 this morning he...breakfast with his kids. A. Are eating. B. Were eating. C. Was eating. D. Is eating

C. Was eating
karena pada kata tersebut menunjukkan keterangan waktu yg sudah berlalu, sehingga menggunakan simple past
simple past memakai tobe was dan were
karena subject nya laki laki maka memakai tobe was

semoga membantu :)

C. Was eating , karna ini adalah past countinous tense . 
Rumusnya S + was + v-ing
