what is "carl sandburg" in the above sentence?

a.) simple object
b.) simple predicate
c.) complete subject
d.) complete predicate

C is the answer. Carl Sandburg is the simple subject because he is the main focus of the simple sentence ‘Carl Sandburg was born’. ’The now famous Carl Sandburg’ is a complete subject. ‘Was born’ is the simple predicate and ‘was born in 1878 in Galesburg, Illinois’ is the complete predicate.

The answer would be d, coherence.
