The correct answer is C. Mexican presidents cannot be reelected after serving six years regardless of job performance
Explanation:
Mexico and the United States are both countries in North America, and both have a democratic representative system with a president at the top of government. However, in terms of presidential terms, these two countries are slightly different. In the case of Mexico, each president is in office for six years and there is no reelection. On the other hand, in the United States, the term length for the presidency is four years and reelection is allowed, although this is limited to one. Thus, the difference between both political systems is "Mexican presidents cannot be reelected after serving six years regardless of job performance".
