Whose personal enmity with Cicero is most directly credited with placing Cicero's name on the proscription lists of 43 BCE?

Explanation

Cicero's fierce public speeches attacking Antony, known as the Philippics, made Antony his bitter enemy, and Antony is traditionally credited as the driving force behind Cicero's inclusion on the proscription lists. Lepidus had no comparable personal quarrel with Cicero, Brutus was Cicero's ally rather than his enemy, and while Octavian also agreed to the proscriptions, ancient sources single out Antony's animosity as the direct cause of Cicero's inclusion.
