Final answer:
Bolívar intended to unite Creoles for independence from Spain and advocated for a strong central government to guide newly independent nations.
Step-by-step explanation:
Simón Bolívar's intentions with his speech to the council of Angostura were to advocate for a republican form of government with a strong central power. Bolívar rejected both monarchy and federalism as he believed Spanish Americans were unprepared for self-government due to civic ignorance, oppression, and vice caused by the Spanish colonial system.
His vision included a powerful executive to guide the newly independent nations and stressed the hope for Spanish American unity, with a league of American nations supporting each other. Therefore, the best answer to the question of Bolívar's intentions is b) Unite Creoles in the cause of independence from Spain.
