Answer

To solve the question "Croaking of frog is", we need to analyze the options provided and understand the behavior of frogs in relation to croaking.

### Step-by-Step Solution:

1. **Understanding Croaking**: Croaking is a distinctive sound produced by frogs. This sound is made using vocal cords and a vocal sac, which are structures that help in sound production.

2. **Identifying the Purpose of Croaking**: Frogs croak primarily during specific times, particularly during the breeding season. The sound serves a significant purpose in their reproductive behavior.

3. **Analyzing the Options**:
- **Call for Food**: Frogs do not croak to signal food; they use other methods to hunt or attract prey.
- **Indication of Enemy**: While frogs may have ways to signal danger, croaking is not primarily used for this purpose.
- **Call for Mating**: This is the most accurate option. During mating season, male frogs croak to attract female frogs. The croaking serves as a mating call.
- **Call for Hibernation**: Frogs do not croak to indicate hibernation; this is not a behavior associated with their vocalizations.

4. **Conclusion**: Based on the understanding that croaking is primarily a mating call, the correct answer is that the croaking of a frog is a **call for mating**.

### Final Answer:
The correct answer is: **Call for mating** (Option 3).
