Following on the successful activism of cesar chavez, mexican american youths began to refer to themselves as
a. los hombres.
b. los barrios.
c. chicanos.
d. mexicans

The correct answer is C. Chicanos.

"Chicano" was originally a pejorative (negative) term for Mexican Americans, especially the ones with an immigrant backgound.

Within the Mexican Americans there was a need for a new identity, and a feeling (both from within and from outside) that they were different both from the Mexican and from other Americans.
This identity, along with a fight for better fighters' rights, was at the heart of the Chicano Movement, which began in the 1940s.  Cesar Chavez was an important activist for this movement.
