Kabir was born in the lowest caste of people, he lived until he was 120 years old and he was immaculately conceived, so the correct answers are A and B.
The second one if correct u have a add A but a lot of people do not add the ''a school' because there lazy like us humans these days so we try to make words easier so we use the first one
I believe it would be sat because its the only verb that connects from the mom to the passenger...i think thats correct...i hope that helps
