Solution

The correct option is C Heterotrophic and autotrophic
The mode of the nutrition of bacteria is usually both autotrophic as well as heterotrophic. They are characterized by the presence of chlorophyll a which is similar to green plants and thus can make their own food, e.g., Nostoc while some show heterotrophic mode of nutrition which requires an organic carbon source for growth and may be parasites, saprophytes or symbionts, e.g., Streptococcus, Clostridium.
So, the correct answer is option C.
