B. In
C. With
D. From

Answer 1

Hint: One of the parts of speech, Preposition is a word used to link nouns, pronouns or any phrases to other words within a sentence. Above question’s solution will have to join or accomplish two different things at the same time.

Complete answer:
After analysing the question, it shows that Alice has completed two tasks at the same time. Plus “killing two birds with one stone” is an idiom. A preposition is a word or group of words used before a noun, pronoun, or noun phrase to show direction, time, place, location, spatial relationships, or to introduce an object.

Now that we know what prepositions are let's view the given options.
Option (A) which has the preposition “by” is not correct. Generally the usage of “by” as a preposition means “next to” or “beside".
Option (B) which has the preposition “In”, is not correct , because it simply doesn’t make any sense, therefore it becomes a grammatical error.
Option ( C) is the correct answer. "Wiith'', means to indicate being together or being involved, which is required in the given sentence to complete it. Thus, Option C is the right answer.
Option (D) which has the preposition “from”, is not the correct option as this preposition is generally used while referring to the start of something. So using this option makes no sense as per the given sentence. Thus, Option D is absolutely wrong.

Hence the correct answer is option ‘C’.

Note: A preposition is a word or group of words used before a noun, pronoun, or noun phrase to show direction, time, place, location, spatial relationships, or to introduce an object. Some examples of prepositions are words like "in," "at," "on," "of," and "to."Prepositions in English are highly idiomatic.
