When plants die, the carbon contained in their biomass undergoes various processes. Here’s what generally happens to the carbon:

1. **Decomposition**: Microorganisms like bacteria and fungi break down the dead plant material, releasing carbon back into the atmosphere as carbon dioxide (CO2) through respiration. This is a significant way that carbon is released into the environment.

2. **Soil Carbon**: Some of the carbon may be incorporated into the soil as organic matter, contributing to soil health and fertility. This organic matter can store carbon for a longer period, depending on various factors such as soil type and conditions.

3. **Fossilization**: In certain conditions, especially in anaerobic environments (like peat bogs or swamps), some carbon may become buried and eventually transform into fossil fuels over millions of years. This is a much slower process.

4. **Inert Matter**: If the plants’ bodies do not decompose completely (for example, in very dry or cold environments), some carbon may remain in the biomass for some time.

So, among the options provided, "The carbon is released into the environment" is the most accurate statement regarding what generally happens to carbon in plants when they die.
