The main reason cárdenas nationalized mexico’s oil industry was to
a. curtail foreign investment in this key resource.
b. end corruption within private oil businesses.
c. enable the country to get direct benefit from its vast supplies.
d. better protect the environment and land in the country.

The correct answer is C. The main reason Cardenas nationalized Mexico's oil industry was to enable the country to get direct benefit from its vast supplies.

Explanation:

Cardenas decreed oil expropriation on March 18, 1938, creating Pemex (Petroleos Mexicanos), a state company that would be in charge of the exploitation. He did so due to a combination of factors, including the weakness of the American and British economies during the 1930s (both were mired in the effects of the Great Depression), the existence of a strong conflict between workers of the oil companies installed in Mexico and the foreign businessmen who neglected a labor award of the Mexican court, as well as their own vision of a democratic and nationalist capitalism, in which the basic industries (oil, steel, etc.) played a key role, so according to his theory should remain in the hands of the government.
