Complete the following sentence with correct Adjective Clause from the options given below:

Spring is the time of the year.

When flowers bloom

The correct answer is Option (4) → When flowers bloom

The complete sentence is: Spring is the time of the year when flowers bloom.

Here's why:

* **Rains very badly:** This is an adverb clause describing how it rains in spring, not an adjective clause describing spring itself.
* **Where water flows:** This could be true in any season, not specific to spring.
* **How she walks:** This is completely unrelated to spring.
* **When flowers bloom:** This clause directly modifies "spring" by specifying a characteristic time of year -  the season when flowers bloom.
