Which type of cargo can be very unstable due to its high center of gravity and therefore requires special handling?

Answer: C — Hanging Meat

The correct answer is hanging meat, as it is a type of cargo that can have a high center of gravity, making it prone to swaying and shifting while in transit. This instability necessitates special handling procedures to ensure safety and prevent accidents. The unique shape and weight distribution of hanging meat require careful loading and securing methods to maintain balance and prevent it from tipping or moving erratically. Other types of cargo listed, like oversized loads, livestock, and dry bulk, also present challenges but generally do not exhibit the same level of instability linked to a high center of gravity. Oversized loads, while requiring special permits and handling due to their dimensions, typically have a lower center of gravity depending on their shape. Livestock require specific care during transport to ensure their safety and well-being, while dry bulk commodities, often distributed evenly in their containers, don't typically involve the high center of gravity scenario that hanging meat does.
