Ineed i am in an online report, hyperlinks a. should be used only for headings and subheadings b. are a useful way to provide access to an appendix that supports one of your arguments c. are considered trendy and should usually be avoided d. complicate the organization of your report by enabling readers to jump from section to section

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
