Question

america became known as what to latin america as it regional influence grew? \abuelita\ \big sister\ \uncle sam\

Explanation:

To determine the answer, we analyze the context of US - Latin America relations. As the US's influence in Latin America grew, it was referred to as "Big Sister" in the region. "Abuelita" (grandmother) and "Uncle Sam" (a symbol of the US domestically, not the term for Latin American perception of US regional influence) do not fit.

Answer:

B. "Big Sister"
