Option 1: Exonerate -> means to clear from blame or accusation, which is the opposite of indict.
Option 2: Praise -> means to express approval or admiration, unrelated to legal charges.
Option 3: Accuse -> means to formally charge with wrongdoing, which aligns with indict.
Option 4: Ignore -> means to disregard or pay no attention to, unrelated to making charges.
Hence, Option 3: Accuse -> "Indict" means to formally charge someone with a crime or offense, making "accuse" the closest synonym as both involve charging someone with wrongdoing -> correct
