Question

read the excerpt from flannery oconnors \the life you save may be your own.\
\a body and a spirit,\ he repeated. \the body, lady, is like a house: it dont go anywhere; but the spirit, lady, is like a automobile: always on the move, always...\
this excerpt contains
○ one simile.
○ two metaphors.
○ two similes.
○ one case of irony.

Explanation:

A simile uses "like" or "as" to compare two unlike things. The excerpt has two such comparisons: 1) "the body... is like a house" and 2) "the spirit... is like a automobile". Metaphors do not use "like"/"as" for direct comparison, and there is no irony present here.

Answer:

two similes.
