Arrange the jumbled words appropriately to form a meaningful sentence:

a. Insulation against cold they act as.
b. They act as insulation against cold.
c. act as insulation against cold they.
d. Act as insulation they against cold.

Hint: To find the correct answer, look for a grammatically correct sentence with a suitable subject.

Complete answer:
To reach the correct answer amongst jumbled words, first look for a subject. Then, look for a verb. Next, look for an object or preposition, if any. Put these together in the normal format of a sentence, which is subject + verb + object. Then, look at the given options.
In the given question, there are two possible nouns, they are the words ‘they’ and ‘insulation’. The verb is the word ‘act’ and ‘as’ is the preposition.
Let us evaluate the options one by one.
- Option ‘A’, is incorrect as there is no verb that follows the subject.
- Option ‘C’, is incorrect as the punctuation in the sentence is wrong. The first letter of the first word of the sentence is not capitalized. It also starts with a verb.
- Option ‘D’, is incorrect as the sentence starts with a verb.

> Hence, the correct answer is option ‘B’, as the sentence follows all the requirements and gives a suitable meaning as well.

Note: When faced with jumbled words, in order to find the answer quickly, try and find the answer by yourself before checking the options available. In this way, there would be some clarity on the subject, object and verb of the sentence and will avoid confusion.
