Answer 2

He leans against a wall.

 

Explanation:

• Propositions are words that refer to a relationship with other words in a sentence.  

• Place of propositions are used to refer to a place, usually to indicate the location of something or someone.  

• As we read the above sentence we understand that "he" leans inclined at the surface of the wall and receives support, then her body weight exerts a force on the wall in the opposite direction from that applied by the wall.  

• So, the most appropriate suitable word is here is "against".

• Thus, the perfect complete sentence is He leans against a wall.
