Explanation
The analogy presented in the question is Cloud : Rain as B: Thunder : Lightning.
Rain is a direct result of clouds, as they contain the water vapor that ultimately condenses and falls to the ground. In the same way, thunder is a direct result of lightning, which is an electrical discharge that occurs within clouds. Thunder is the sound that results from the rapid expansion of the air around the lightning bolt.
The other options are not related in the same way as the given analogy. Wind can cause a hurricane, but it is not a direct cause-and-effect relationship. Water is the chemical composition of rain, but it is not an analogy of cloud and rain. Sky and universe are too broad to create a meaningful analogy with rain and cloud.
Therefore, the correct answer is B: Thunder : Lightning.
