William and Benjamin are forensic science students. They are studying a case where a body was found in a forest. They are trying to determine the time of death by examining the decomposition stage of the body. They concluded that the body is in the third stage of decomposition. What is this stage called?

• active decay

• dry or skeletal

• advanced decay

• fresh stage

• bloating

• bloating

• fresh

• dry or skeletal

• active decay
