In which stage do bacteria remain dormant?

1. Active stage

2. Spore stage

3. Inactive stage

4. Reproductive stage

The correct answer is: Inactive stage

The correct choice is the spore stage. During this stage, bacteria form spores, which are highly resilient structures that enable them to withstand extreme environmental conditions. Spores allow bacteria to remain dormant for extended periods, protecting them from factors such as heat, radiation, and desiccation. This dormant state is a survival mechanism, enabling bacteria to endure adverse conditions until they become favorable for growth and reproduction. While the inactive stage might seem like a valid choice for dormancy, it doesn't specifically denote the formation of spores, which is a key characteristic of bacterial survival. The active stage signifies that bacteria are metabolically active and reproducing, while the reproductive stage refers to the process where bacteria divide and multiply. Each of these stages reflects a different aspect of bacterial life and activity.
