Fill in the blank with the most appropriate word.
Take your umbrella. It ___.

Solution(By Examveda Team)

In the given sentence "Take your umbrella. It rained," the most appropriate word to fill in the blank is "rained."

The sentence is in the past tense and describes a past event of rain. The verb "rained" is the simple past tense form of "rain," which indicates an action that occurred and was completed in the past.

The other options are not suitable for this sentence. Option A, "was raining," is in the past continuous tense, which implies an ongoing action in the past rather than a completed event. Option C, "rains," is in the present tense and does not match the past context of the sentence. Option D, "is raining," is in the present continuous tense and also does not fit the past tense context of the sentence.

Therefore, the correct answer is "B. rained."
