Identify the use of the italicized noun clause. i found ( what i was looking for) in my purse. (a) subject complement (b) direct object (c) subject

The italicized noun clause is used as B. direct object in this sentence.
It is relatively easy to spot a direct object in a sentence - just ask the question what/whom? So - What did I find? - What I was looking for.
There is no subject complement here, and the subject is the pronoun I.

Is there more to this?
