Answer : D

Prepositions are words that indicate relationships with the other words in the sentence. Prepositions of place are used to refer to a place, usually to denote the location of something or someone.

Let's look at the usage of various alternatives in the option as preposition of place:

• to : means "in a particular direction"
• with : means "accompanied by (something or someone)"; or "in relation to"
• on : to refer to placement of something attached / adjacent to something else; to refer to something displayed on something else
• about : to refer to a particular subject of conversation; to express a location in a particular place
  

In the sentence, the speaker is asking the other person regarding what subject did he / she had talked. Therefore, "about" is the most suitable preposition here.

Thus, the correct complete sentence is:

"What did you talk ABOUT ?"
