Explanation

To solve the question "Find out the correct statement," we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Analyze Option A: Strobilanthus kundiana flowers only once a year.**
- The plant Strobilanthus kundiana, also known as Neelakuranji, is known for flowering once every 12 years, not once a year. Therefore, this statement is incorrect.

2. **Analyze Option B: Monkeys and apes show cyclical changes during reproduction called estrous cycle.**
- Monkeys and apes do exhibit reproductive cycles, but they are referred to as menstrual cycles, similar to humans. The estrous cycle is typically associated with other mammals like dogs and cats. Thus, this statement is also incorrect.

3. **Analyze Option C: Bamboo species flower only once in their lifetime.**
- Bamboo species do indeed have a unique flowering behavior where they flower only once in their lifetime, which can be every 10 to 120 years depending on the species. This statement is correct.

4. **Analyze Option D: All of the above.**
- Since options A and B are incorrect, this statement cannot be true.

### Conclusion:
The correct statement is **Option C: Bamboo species flower only once in their lifetime.**
