The given syllogism is a valid example of a categorical syllogism in the form of "A is only B if C", which can be rewritten into standard form as "All A are C, and all non-C are non-B". In this case, "A" refers to uncontrollable boys, "B" refers to non-controllable boys, "C" refers to boys with good parenting, and "non-C" refers to boys without good parenting. Therefore, the conclusion that can be drawn from the syllogism in standard form is "All controllable boys are choirboys", which corresponds to answer choice C.
