Complete solution:
In the given question, we have to find out which of the options includes a preposition that introduces the subject, which in this case is homework.
Let us thus analyze the options given to us in this question -
Option (a.), 'of', refers to ‘Introducing subject matter’. Therefore, option (a.) is correct as it introduces the subject ‘homework’.
Option (b.), ‘on', refers to ‘Positioned at the upper surface of, touching from above’. Therefore, option (b.) is incorrect as it does not introduce the subject ‘homework’.
Option (c.), ‘at', refers to ‘In or very near a particular place’. Therefore, option (c.) is incorrect as it does not introduce the subject ‘homework’.
Option (d.), ‘about', refers to ‘(of quantities) imprecise but fairly close to correct. Therefore, option (d.) is incorrect as it does not introduce the subject ‘homework’.
Hence the correct answer is option ‘a’.
