Fill in the blank with a suitable preposition.
Kim's mother complained that he is reading comics from morning _______ night.
The given sentence discusses the duration that Kim spends in reading. Therefore the preposition ‘to’ would be the apt option since ‘to’ is used to signify the end of a period. Hence option C is correct. On the other hand the prepositions ‘after’, ‘since’ and ‘at’ are irrelevant in the given context. ‘After’ is used to speak about an action that follows another action which is not the case here. The sentence clearly mentions a period through the use of the preposition ‘from’. Similarly ‘since’ is used to indicate the beginning of an action or period. Whereas the preposition ‘at’ is used to speak about a specific time, which is not the case here. Therefore options A, B, and D are incorrect.
