Composite cable is defined by containing more than one type of transmission medium. When a cable includes both optical fiber and copper conductors, its description is fiber and copper. That directly identifies what the cable contains, which is why this option is the best fit. A related term you might hear is hybrid cable, which means the same idea in practice, but the question is asking for the materials inside, not what the cable is called. The other options refer to concepts that don’t describe the materials inside: singlemode and multimode are fiber types, filled refers to a substance inside the cable, and hybrid cable describes the combination rather than listing the actual constituents.
