Why each option
CAT6 (Category 6) Ethernet cable contains four twisted pairs of copper wire, the same physical construction as CAT5e.
Two twisted pairs (4 conductors) was used in older telephone wiring and some legacy Ethernet implementations, not CAT6.
CAT6 cabling consists of four twisted copper pairs (8 conductors total), which is the standard for all modern Ethernet UTP cabling categories including CAT5, CAT5e, CAT6, and CAT6a. The improvement in CAT6 over earlier categories comes from tighter twisting and a spline separator, not additional pairs.
Six twisted pairs do not correspond to any standard Ethernet copper cabling category; the number 6 in CAT6 refers to the category, not the pair count.
Eight twisted pairs (16 conductors) is not a standard configuration for CAT6 UTP cabling.
Sixteen pairs is not a standard for any Ethernet copper cabling category.
