Explanation: The correct preposition to use with 'insisted' in this context is 'on,' and the gerund form 'my going' is used to denote action. Correct: A. Incorrect options: B. 'is to go' is grammatically invalid here. C. 'over going' is incorrect as it does not align with the verb 'insist.' D. 'to go' is not suitable as it does not match the verb's construction.
