Final answer:
Option C, 'The support for Spanish rule unified groups,' is not true. Social groups under Spanish colonial rule did not unite in support of Spain; instead, their grievances against the rigid social hierarchy and desire for independence eventually led to revolutionary movements.
Step-by-step explanation:
Among the options provided regarding Creoles, Mestizos, Native Americans, and Enslaved Africans, the one that is not true is C. The support for Spanish rule unified groups. In the social hierarchy of colonial Latin America, there were clear divisions and resentments among the various social groups due to the rigid social structure. The peninsulares and creoles controlled political and economic power, while mestizos, mulattoes, natives, and enslaved Africans occupied the lower strata. These imbalances, along with the influence of Enlightenment ideas, shifted sentiments towards discontent and the rise of revolutionary ideals. Groups did not feel a unifying support for Spanish rule; rather, the oppression experienced under Spanish colonialism was a common factor contributing to the desire for independence among the colonies.
