Read the following scenario and answer the three questions that follow.

Rohini is one of the most popular faculty members in the finance department, known for her in-class engagement with students. Every year, she offers an elective Financial Risk and Derivatives Management in the fourth term which gets subscribed by about hundred students. This year, owing to Covid-19, she is forced to teach the course online, that too, in the fifth term. The fifth term is notorious for its non-negotiable teaching slots. To enable her teaching, Rohini uses her favourite laptop, Maplebook Lite, sold by Maple.

Rohini converts her family bedroom into a “working room” because of the strong wifi signals. The room is mostly used by Rohini for taking her classes; however, Rinku, her husband, also uses it for running his meetings. Rohini has two children, aged 5 and 8, who use the living room as their playground. During meetings and classes, the working room is shut to save it from unwanted disturbance and noises from the living room.

It is 3:10 p.m. and Rohini’s penultimate session of the course is going to end in twenty minutes. As usual, Rinku enters the room with a cup of Darjeeling tea. Just before entering, he asks his kids to stop playing for some time. He quietly places the teacup on Rohini’s study table and exits the room, leaving the door ajar. As soon as he leaves, a tennis ball comes thundering inside, crashing into her Maplebook monitor. The monitor breaks and Rohini’s class ends abruptly, much before the scheduled time.
