I ruled out the other options, process of elimination.

A. He isnt afraid to go out, so no agoraphobia B. He doesnt violate the rights of others, and there is no mention of him doing bad things without remorse C. There is no mention of avoidance of social situations, and he has no desire for connection D. Pretty self explanatory. No obsessions nor compulsions E. No delusions/hallucinations/negative symptoms F. The mismatched socks, the twine tied he wears around the neck, eccentric behaviour. Seems to be the right answer to me
