Why each option
A rack unit (U) defines the vertical space occupied by equipment in a server rack, where 1U is precisely 1.75 inches (4.445 cm) tall.
A server with a height of 1.75 inches directly corresponds to the standard definition of 1U, which is 1.75 inches (4.445 cm).
2U represents a height of 3.5 inches (2 * 1.75 inches), not 1.75 inches.
3U represents a height of 5.25 inches (3 * 1.75 inches), not 1.75 inches.
5U represents a height of 8.75 inches (5 * 1.75 inches), not 1.75 inches.
