The correct option is C) less trusting of governmental institutions and leaders

Explanation:

The erosion of trust for the government began among the U.S people in the 1950's. After the events like the Vietnam War, civil unrest and the Watergate scandal, the trust became even more scarce.

Every generation which has come after the 1950s has been more and more mistrusting. With the advancements in media, every person now knows the strategies which arise in politics and the manipulative nature of many of the politicians. Hence, this has lead to less trusting of governmental institutions and leaders.
