Question

Why are you always so rude ______ your parents?
A. At
B. Of
C. To
D. By

Answer 1

Hint: A preposition is a word used within a sentence to attach nouns , pronouns, or phrases to other words. They work to link a sentence's people, things, time and locations. The first known use of preposition was in the 14th century.

Complete answer:
Prepositions are commonly short words, and they are usually put in front of nouns directly. It is a term that normally combines with a noun phrase to form a phrase that generally communicates a prediction or modification.

Prepositions signify direction, time, place, space and other abstract kinds of relationships. Let us look at examples for each. The prepositions are in italics for your convenience.
Direction: Look to the left and you will see our destination.
Time: We have been working since this morning.
Location: We saw a movie at the theater.
Space: The dog hid under the table.

The sentence given shows the path of rudeness. Consequently, 'to' is the acceptable answer, because 'to' is used to reflect a certain direction. Option C is therefore right. Whereas, 'at' is used to illustrate a certain location, so option A is unacceptable. The 'of' preposition is used to express the feeling of belonging or some relationship, while 'by' is used to represent how a work is performed. Since the sentence talks about the path of something, in the given sense, 'of' and 'by' are inappropriate. The B and D alternatives are also wrong.

Hence the correct answer is option ‘C’

Note: If you get confused about which preposition will fit the best in the given blank, always refer to its relation with the noun. You can always look up in grammar books for better understanding.
