a. the name given to mexican immigrants in texas.
b. a style of dance popularized by mexican americans.

Tex-Mex is specifically a type of cuisine - the correct answer is

c. a combination of two cuisines of Texas and Mexico.

It's a version of Mexican cuisine after a contact with Texas cuisine and American cuisine.

Incidentally, it is also the best example of a cultural blend from all the options, as the other options don't mention any cultural blend

the answer is       political office
