(a)For
(b)Upon
(c)Of
(d)On

Hint: Read the given sentence carefully. Try to make out the core meaning of it. Find out the subject, predicate and the object of the given sentence.

Complete answer: The given sentence conveys that Tim was accused of something that he didn’t do, for stealing his aunt's necklace. To be accused is a person who is charged with or on trial for a crime. Here, we have to fill in the given blank with the correct prepositions from among the four given options.
Now, let us examine all the given options to find out the correct option :
(a)for-It is a preposition which means used to indicate a place. It cannot be the correct option and cannot be filled in the given blank.
(b)upon-It is a preposition which is a more formal term for ‘on’, especially in abstract sentences. It is also an incorrect option.
(c)Of-It is a preposition which means belonging to, connected with, a part of something/somebody. It is the correct option.
(d)On-It is a preposition which means supported by, fixed to or touching something, especially a surface.
As we have analysed all the given options, we can easily figure out the correct Here, the correct word to be filled in the blank is – of. Hence, option ‘c’ is the correct option.

Note: All the other options are plausible distractions. Don’t confuse between ‘for’ and ‘of’. ‘For’ is used to point out any distance or place, unlike ‘of’.
