Hint: Read the given sentence carefully and understand what it means. Now go through the given options and choose the one which fits the context of the sentence and expresses it the best. You can also use the hit and trial method to choose the appropriate answer.

Complete answer: In the given question, we have to fill in the blank with the most appropriate preposition from among the four given options. A preposition is a word governing, and usually preceding, a noun or pronoun and expressing a relation to another word or element in the clause, as in ‘the man on the platform’, ‘she arrived after dinner’, ‘what did you do it for ?’.
Now, let us examine all the given options to find out the correct answer :
Option ‘a’ is With. It is a preposition which means to be accompanied by (another person or thing). For example: “a nice steak with a bottle of red wine”
Option ‘b’ is In. It is a preposition which is used in expressing the situation of something that is or appears to be enclosed or surrounded by something else. For example: “I’m living in London”
Option ‘c’ is On. It is a preposition which means - physically in contact with and supported by (a surface). For example: "on the table was a water jug"
Option ‘d’ is Of. It is a preposition which means - expressing the relationship between a scale or measure and a value. For example: “an increase of 5%”
Hence, option ‘b’, in, is the correct option.

Note: Prepositions don’t usually have the same meaning in every sentence. Its meaning changes with the context of different sentences.
