Answer: d. Spain.
Explanation: While Spain is a Spanish-speaking country, it is considered the origin of Hispanics, not Latinos.
Latinos primarily originate from countries in Latin America, which includes countries in Central and South America. Brazil, Mexico, and Costa Rica are all countries in Latin America and are considered the origin of Latinos.
It's important to note that the terms "Hispanic" and "Latino" are often used interchangeably, but they have slightly different meanings. "Hispanic" refers to people from Spanish-speaking countries, including Spain, while "Latino" refers to people from Latin American countries.
