a. It defeated opposition parties by controlling congress and using election fraud.

Explanation:

PRI was the Mexican political party that governed most political institutions since it was established in 1929 and until the end of the millennium. Even though the PRI was able to gain the backing of many citizens, it did use repression and electoral fraud to strengthen its situation. Such is the case of the violent suppression of student demonstrations in the 1970s and the fraudulent elections during the ´80s and ’90s.
