Option 1 (havoc) -> Means widespread chaos/destruction, which would be a disturbing but expected response to poll rigging in an autocratic regime.
Option 2 (jubilation) -> Means celebration/joy, which contradicts the "disturbing" nature of the event described.
Option 3 (excitement) -> Means enthusiasm, which is too positive and doesn't align with something "disturbing."
Option 4 (mayhem) -> Means violent disorder/chaos, which similarly describes a disturbing but predictable reaction to electoral fraud.
Hence, Options 1 and 4 (havoc/mayhem) -> Both words are synonymous and appropriately describe the chaotic, disturbing unrest that would follow rigged elections in an autocratic regime. "Havoc" and "mayhem" both convey destruction and disorder, making them contextually fitting for the negative aftermath of electoral manipulation -> correct
