Marge Believes Rather Strongly That More Money Should Be Devoted

Marge believes rather strongly that more money should be devoted to environmental concerns.

She then seems to soften her stance about the environment. This is best explained by

A) cognitive dissonance theory.
B) self-affirmation theory.
C) the inoculation hypothesis.
D) self-perception theory.
