Final answer:
A laptop will consume approximately 5 GB to 15 GB of data for 5 hours of online classes.
Step-by-step explanation:
The amount of data consumed during online classes can vary depending on factors such as video quality and internet speed. On average, streaming video at standard definition (SD) uses about 1 GB of data per hour, while streaming at high definition (HD) can use up to 3 GB per hour.
Considering this, for 5 hours of online classes, a laptop would consume approximately 5 GB to 15 GB of data, depending on the quality of the stream. Therefore, the correct answer would be d) 15 GB, as it represents the maximum amount of data that could be consumed.
