Answer:
Subject - 'What I wanted to do'
Explanation:
Noun clause is described as the group of words which functions as a noun in the sentence. This clause is dependent and may function as subject, indirect object, subject complement, object of preposition, direct object, etc.
In the given sentence, the italicized noun clause 'What I wanted to' is functioning as the subject in the sentence as it is the primary element that is being discussed in the sentence. The action 'was to finish' is performed by it only and hence, it is the subject.
