Solution
The correct option is A Endospores Endospores are dormant, tough, thick-walled bacterial cells produced by certain bacteria during adverse environmental conditions. The center of the endospores is in dehydrated form and contains DNA and dipicolinic acid. The calcium-dipicolinic acid complex protects the cells from heat.
